[ARC] Add support for profiling in glibc.
Use PROFILE_HOOK to add mcount library calls in each toolchain.
gcc/
xxxx-xx-xx Claudiu Zissulescu <claziss@synopsys.com>
* config/arc/arc.h (FUNCTION_PROFILER): Redefine to empty.
* config/arc/elf.h (PROFILE_HOOK): Define.
* config/arc/linux.h (PROFILE_HOOK): Likewise.
