abd0cdc9c0 Hide __cpu_indicator_init/__cpu_model from linker
We shouldn't call external function, __cpu_indicator_init, while an object
is being relocated since its .got.plt section hasn't been updated.  It
works for non-PIE since no update on .got.plt section is required.  This
patch creates libgcc.so as a linker script, hides __cpu_indicator_init
and __cpu_model in libgcc.so.1 from linker, forces linker to resolve
__cpu_indicator_init and __cpu_model to their hidden definitions in
libgcc.a while providing backward binary compatibility.

b6530d0a50 [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'

    nvptx-as: ptxas returned 255 exit status
