[PATCH] libgcov: Call __builtin_fork instead of fork

[Florian Weimer]

Some targets do not provide a prototype for fork, and compilation now
fails with an implicit-function-declaration error.

libgcc/

        * libgcov-interface.c (__gcov_fork):

Generated code is the same on x86_64-linux-gnu.  Okay for trunk?

Thanks,
Florian
