  * Merge with Debian; remaining changes:
    - Build from upstream sources.
    - Build binutils-static and binutils-static-udeb packages.
    - Don't build cross binutils packages for Debian ports architectures.

binutils (2.25.51.20151106-1) experimental; urgency=medium

  * Snapshot, taken from the trunk 20151106.
  * Work around PR ld/19188, internal linker error. LP: #1511542.
