testsuite: introduce hostedlib effective target

Several C++ tests fail with --disable-hosted-libstdcxx, whether
because stdc++exp gets linked in despite not being built, because
standard headers are included but that are unavailable in this mode,
or because headers are (mistakenly?) expected to introduce
declarations such as for abort, malloc, etc, but in this mode they
don't.

This patch introduces an effective target for GCC test, equivalent to
one that's available in the libstdc++-v3 testsuite, and arranges for
all such tests to be skipped when libstdc++-v3 is not hosted.
