The experimental-library-flag.cpp test was failing on FreeBSD builders, which turned to be caused by missing support for -stdlib=libcstdc++ (and just using a hardcoded libc++ in all cases). Simplify FreeBSD::AddCXXStdlibLibArgs() by deferring to the parent class and dealing with the FreeSBD < 14 profiling support as a special case. While touching the test file also drop the unnecessary `-o %t.o`. This is not needed since the RUN lines use -### and don't produce any output.
