GCN, nvptx: Don't default-disable libstdc++ build
In addition to making libstdc++ itself available, this, via enabling
'build-gcc/*/libstdc++-v3/scripts/testsuite_flags', in particular also makes
the standard C++ headers available to 'make check-gcc-c++'. With that, there
are a lot of FAIL/UNRESOLVED -> PASS progressions, where we previously ran
into, for example:
FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for errors, line 6)
FAIL: g++.dg/coroutines/co-await-syntax-00-needs-expr.C (test for excess errors)
Excess errors:
[...]/gcc/testsuite/g++.dg/coroutines/coro.h:132:10: fatal error: cstdlib: No such file or directory
Similarly, there are a lot of FAIL/UNRESOLVED -> UNSUPPORTED "progressions" due
to 'sorry, unimplemented: exception handling not supported'.
The 'make check-target-libstdc++-v3' results don't look too bad, either.
This also reverts Subversion r221362
(Git commit d94fae044da071381b73a2ee8afa874b14fa3820) "No libstdc++ for nvptx",
and commit 2f4f3c0e9345805160ecacd6de527b519a8c9206 "No libstdc++ for GCN".
With libstdc++ now available, libgrust gets enabled, which we in turn again
have to disable, for 'sorry, unimplemented: exception handling not supported'
reasons.
