libgcov: Fix build on Darwin [PR99406]
As reported, bootstrap currently fails on older Darwin because MAP_ANONYMOUS
is not defined.
The following is what gcc/system.h does, so I think it should work for
libgcov.

* libgcov.h (MAP_FAILED, MAP_ANONYMOUS): If HAVE_SYS_MMAN_H is
defined, define these macros if not defined already.
