Subject: testsuite: add hostedlib requirements to multiple C++ tests
X-Git-Tag: basepoints/gcc-17~1859
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=dd55243e3506903fa976967bc6d573edcb8eb43d;p=thirdparty%2Fgcc.git

testsuite: add hostedlib requirements to multiple C++ tests

Various C++ tests added in the gcc-15 cycle require features that are
only available when libstdc++-v3 is built in hosted mode, so they fail
when this is not the case.  Skip them if ! hostedlib.
