eglibc 2.16-0ubuntu1 source package in Ubuntu

Changelog

eglibc (2.16-0ubuntu1) raring; urgency=low

  * Merge with unreleased 2.16 in Debian experimental, remaining changes:
    - Drop the Breaks line from libc6, which refers to a Debian transition
    - Remove the libc6 recommends on libc6-i686, which we don't build
    - Enable libc6{,-dev}-armel on armhf and libc6{-dev}-armhf on armel
    - Ship update-locale and validlocale in /usr/sbin in libc-bin
    - Don't build locales or locales-all in Ubuntu, we rely on langpacks
    - Heavily mangle the way we do service restarting on major upgrades
    - Use different MIN_KERNEL_SUPPORTED versions than Debian, due to
      buildd needs.  This should be universally bumped to 3.2.0 once all
      our buildds (including the PPA guests) are running precise kernels
    - Build i386 variants as -march=i686, build amd64 with -O3, and build
      ppc64 variants (both 64-bit and 32-bit) with -O3 -fno-tree-vectorize
    - Re-enable unsubmitted-ldconfig-cache-abi.diff and rebuild the cache
      on upgrades from previous versions that used a different constant
    - debian/patches/any/local-CVE-2012-3406.diff: switch to malloc when
      array grows too large to handle via alloca extension (CVE-2012-3406)
    - Build generic i386/i686 flavour with -mno-tls-direct-seg-refs
  * Changes added/dropped with this merge while reducing our delta:
    - Stop building glibc docs from the eglibc source, and instead make
      the glibc-docs stub have a hard dependency on glibc-doc-reference
    - Remove outdated conflicts against ancient versions of ia32-libs
    - Drop the tzdata dependency from libc6, it's in required and minimal
    - Use gcc-4.7/g++-4.7 by default on all our supported architectures
    - Save our historical changelog as changelog.ubuntu in the source
    - Drop nscd's libaudit build-dep for now, as libaudit is in universe
    - Drop the unnecessary Breaks from libc6 to locales and locales-all
    - Ship xen's ld.so.conf.d snippet as /etc/ld.so.conf.d/libc6-xen.conf
  * Disable hard failures on the test suite for the first upload to raring

      sotruss.
  * debian/patches/all/local-remove-manual.texi: Update stub manual/Makefile
    with version from eglibc 2.16 upstream.
  * debian/rules.d/quilt.mk: Update refresh target to pop all patches before
    repushing and refreshing them, since patches are applied by default now.
  * debian/rules: Expand clean target to remove several autogenerated files
    under debian/ that weren't getting removed.

  [ Wookey ]
  * Add arm64 support (Closes: #690873):
    - debian/patches/all/unsubmitted-autoconfupdate.diff: Update autotools
      config.sub and config.guess to detect aarch64/arm64 correctly
    - debian/patches/arm64/submitted-aarch64-support.diff: Massive backport
      of the current state of arm64 support upstream and on libc-alpha.
    - debian/patches/arm64/submitted-bits-fcntl_h-at.diff: Include AT_*
      definitions in sysdeps/unix/sysv/linux/aarch64/bits/fcntl.h
    - debian/sysdeps/arm64.mk: Define base arm64 libc targets.
    - debian/rules.d/control.mk: Add arm64 to the list of libc_arches.
    - debian/control.in/main: Build-depend on gcc-4.7 for arm64 builds.
  * debian/rules: Clean up base/cross compiler mangling to work sanely.
  * debian/sysdeps/linux.mk: Define bootstrap BUILD_PROFILE without selinux.

  [ Adam Conrad ]
  * debian/debhelper.in/{libc-bin.install,libc-dev-bin.install}: install
    sotruss binary to libc-dev-bin instead of libc-bin.
  * debian/sysdeps/{i386,amd64,x32}.mk: Don't set MIN_KERNEL_SUPPORTED
    explicitly, as this will cause serious upgrade headaches, and there's
    no guarantee that a 3.4.0 kernel actually has x32 support built in.
  * debian/control.in/main: Bump the linux-libc-dev build-dep to (>= 3.4)
    on all linux-any architectures, not just amd64, i386, and x32.
  * debian/debhelper.in/libc-bin.manpages: Add a pldd(1) manpage.
  * Drop patches/any/cvs-malloc-arena.diff, included in our new upstream.
  * debian/sysdeps/{i386,amd64}.mk: Comment out x32 multilib builds until
    we've reached a consensus about bootstrapping this into the archive.
  * Version gcc-4.7 build-deps to get a version that works for eglibc.
  * debian/sysdeps/*: clean up use of CC and CXX to match wookey's fixes.
  * debian/control.in/libc: Update nscd/locales breaks to (<< 2.16)
  * debian/rules: Unset CFLAGS and friends and use the package versions.
  * Move ldconfig to ldconfig.real, install ldconfig wrapper, and set up
    a dpkg trigger for libc-bin to avoid excessive calls to ldconfig
  * Don't build nscd during when doing a bootstrap DEB_BUILD_PROFILE
  * Make our DEB_BUILD_PROFILE=bootstrap support look more like Ubuntu's
    previously known-working DEB_STAGE=stage1 support for the time being.
  * debian/rules.d/build.mk: If WITH_SYSROOT is passed to debian/rules,
    then pass --with-headers=$(WITH_SYSROOT)/$(includedir) to the build.
  * Sync support for armel/armhf biarch packages, but keep it disabled.
  * Adjust libc.posinst and libc.preinst service restart code for 2.16.
  * Merge regression/progression test suite improvements from Ubuntu.
  * Provide backward compatibility for DEB_STAGE->DEB_BUILD_PROFILE.
