GCN, libstdc++: '#define _GLIBCXX_USE_WEAK_REF 0' [PR119369]
This fixes a few hundreds of compilation/linking FAILs (similar to PR69506),
where the GCN/LLVM 'ld' reported:
ld: error: relocation R_AMDGPU_REL32_LO cannot be used against symbol '_ZGTtnam'; recompile with -fPIC
>>> defined in [...]/amdgcn-amdhsa/./libstdc++-v3/src/.libs/libstdc++.a(cow-stdexcept.o)

..., which is:
$ c++filt _ZGTtnam
transaction clone for operator new[](unsigned long)
..., and similarly for other libitm symbols.
However, the affected test cases, if applicable, then run into execution test
FAILs, due to PR119369
"GCN: weak undefined symbols -> execution test FAIL, 'HSA_STATUS_ERROR_VARIABLE_UNDEFINED'".

* config/cpu/gcn/cpu_defines.h: New.
* configure.host [GCN] (cpu_defines_dir): Point to it.
