Yes, something like this:
--- a/libstdc++-v3/testsuite/17_intro/headers/c++1998/all_attributes.cc
+++ b/libstdc++-v3/testsuite/17_intro/headers/c++1998/all_attributes.cc

#define abi_tag 1
But it's a bit fragile, as the list of C headers might vary between darwin
versions. This would be more reliable, and we still test that libstdc++ doesn't
use those names on all other targets:
