Dear Maintainer,
Currently the manpage for ld.so contains some of the magic strings for
proper subfolder names. However this list does not seems to reflect the
current glibc (bullseye system) release.
Typically:
% sudo ldconfig -p | grep hwcap
libx264.so.160 (libc6,x86-64, hwcap: 0x0004000000000000) => /lib/x86_64-linux-gnu/haswell/libx264.so.160
libx264.so.160 (libc6,x86-64, hwcap: 0x0000000000000004) => /lib/x86_64-linux-gnu/avx512_1/libx264.so.160
It would be nice to document the latest known valid subfolder names
handled by ldconfig.
