Re: [PATCH] add support for GCC 9 attribute copy
Samuel, could you look at the build failures for i686-gnu with mainline
GCC after this GCC change?
../sysdeps/mach/hurd/dl-sysdep.c:286:26: error: '__check_abort_no_hidden' specifies less restrictive attributes than its target 'abort': 'cold', 'leaf', 'noreturn', 'nothrow' [-Werror=missing-attributes]
(and a series of further such errors).
Supposing that the latest GCC change fixes the s390x-linux-gnu build
failure, it's possible the i686-gnu failure is the last one remaining from
this issue. (ia64-linux-gnu still fails to build with GCC mainline in the
build-many-glibcs.py logs, but that's a separate ICE building libstdc++,
reported at <https://gcc.gnu.org/ml/gcc-patches/2018-09/msg01052.html> and
