--- Comment #1 from Felix Riemann <Felix.Riemann at sma dot de> ---
Patch sent to libc-alpha:
https://sourceware.org/pipermail/libc-alpha/2022-October/142771.html

It will fix configure to keep ARMv7 optimizations enabled:

$ CFLAGS="-O2 -march=armv8-a" ../configure --prefix=/usr
--host=arm-linux-gnueabi
configure: loading site script /usr/share/site/x86_64-unknown-linux-gnu
