[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 : Type or
alignment of argument does not match formal parameter 'ptr'
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
nvptx-as: ptxas returned 255 exit status
make[2]: *** [_gcov_indirect_call_topn_profiler.o] Error 1
..., "dumb down" the libgcc build:
