x86: tst-cpu-features-supports.c: Update AMX check
Pass "amx-bf16", "amx-int8" and "amx-tile", instead of "amx_bf16",
"amx_int8" and "amx_tile", to __builtin_cpu_supports for GCC 11.

* Tue May 4 2021 Florian Weimer <fweimer@redhat.com> - 2.33.9000-4
- Various changes to get glibc building again, using selected upstream
backports.
- Re-enable -Werror by default.
- This release introduces __libc_start_main@@GLIBC_2.34, so binaries
are not compatible with glibc 2.33. Building binaries against this
glibc version is not recommended because of the partial libpthread
transition.
- glibc-upstream-amx-detection.patch: Fix build failure after GCC 11.1 update.
- glibc-upstream-malloc-test-hang.patch: Avoid test hang due to
annobin/binutils bug (#1951492)
* Wed Mar 03 2021 Arjun Shankar <arjun@redhat.com> - 2.33.9000-3
- Drop glibc-rh819430.patch; fixed upstream.
- Auto-sync with upstream branch master,
