In-Reply-To: <20220110213540.1258344-5-goldstein.w.n@gmail.com> (Noah Goldstein via Libc-alpha's message of "Mon, 10 Jan 2022 15:35:38 -0600")

I'm seeing erroneous behaviour with this.  There are random cases of
misbehaviour on build workers with AVX2, for example:

https://build.opensuse.org/package/live_build_log/home:Andreas_Schwab:glibc/glibc:cross-riscv64/f/x86_64

riscv64-suse-linux-gcc: error: unrecognized command-line option '-frounding-math'
make[2]: *** [../o-iterator.mk:9: /home/abuild/rpmbuild/BUILD/glibc-2.35.9000.58.g7912236f4a/cc-base/time/tzset.o] Error 1
