Can semihosting be used with an empty C project?

I seem to get make errors when building ussing a project that started out as an empty c-project instead of the standard "STM32F4xx C/C++ Project" provided by launchpad, and I am realizing the only difference between the two is that, though I specify building a c project from the menu system in eclipse, the launchpad project is actually using a c++ linker instead of a c linker. Because of dependencies I cannot port my code over to a launchpad project. So I was wondering if the errors I am receiving is because semihosting cannot be used with a C Linker? I followed this guide to add semihosting to my project:

http://mcuoneclipse.com/2014/09/11/semihosting-with-gnu-arm-embedded-launchpad-and-gnu-arm-eclipse-debug-plugins/

(with openOCD)

and this is the make line that I am using:

arm-none-eabi-gcc -mcpu=cortex-m4 -mthumb -mthumb-interwork -mfloat-abi=softfp -mfpu=fpv4-sp-d16 -O0 -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections -Wunused -Wuninitialized -Wall -Wextra -Wmissing-declarations -Wconversion -Wpointer-arith -Wpadded -Wshadow -g -T STM32F4.ld -nostartfiles -Xlinker --gc-sections -L"/home/xxxxxxx/Desktop/Development/workspace/c/aib-development/lib/ld" -Wl,-Map,"test.map" -Xlinker --cref --specs=nano.specs -u _printf_float -u _scanf_float --specs=rdimon.specs -o "test.elf" <all the object files >

the only error I am getting is:
librdimon_s.a(rdimon-syscalls.o): In function `_sbrk':
syscalls.c:(.text._sbrk+0x30): undefined reference to `end'
collect2: error: ld returned 1 exit status

Thank you for your time
