I don't think these tests should go in glibc until:
(a) they work with some checked-in mainline GCC version (i.e., if they
need the GCC patches you posted, those are on GCC trunk);
(b) it's clear what GCC and binutils versions are needed for the tests to
work (e.g. "GCC 5 or later, trunk revision NNNNNN or later; binutils
commit 89abcdef or later").
