[PATCH] libstdc++, testsuite: Add a prune expression for external tool bug.

Depending on the permutation of CPU, OS version and shared/non-
shared library inclusion, we get can get warnings from the external
tools (ld64, dsymutil) which are not actually libstdc++ issues but
relate to the external tools themselves.  This is already pruned
in the main testsuite, this adds it to the library.

tested on x86_64, i686 darwin17 which is one of the platforms where
the issue shows.

OK for master? / eventual backports ?
thanks
