There are two C files in the libstdc++ testsuite, this skips them when
-std=gnu++NN or similar appears in the options, to avoid FAILs due to
cc1: warning: command line option ‘-std=c++11’ is valid for C++/ObjC++ but not
for C
* testsuite/18_support/bad_exception/23591_thread-1.c: Skip test if
options are present that aren't valid for C.
* testsuite/abi/header_cxxabi.c: Likewise.
Tested x86_64-linux, committed to trunk.
