[PR target/65181] nvptx libgcc: Prevent building "advanced" stuff (for example, gcov support)
When building GCC against a proper newlib sysroot, the libgcc build will
include more than what's built in the -Dinhibit_libc configuration used when
building newlib as part of the GCC build process. See the inhibit_libc logic
in gcc/configure.ac.
To avoid...

ptxas _gcov_indirect_call_topn_profiler.o, line 101; error : Call has wrong number of parameters
ptxas _gcov_indirect_call_topn_profiler.o, line 101; error : Type or alignment of argument does not match formal parameter 'size'
ptxas fatal : Ptx assembly aborted due to errors
