Subject: [PATCH] make: use `readelf` for LLVM symbol version detection
 (#54713)

Apparently on some distributions `nm --with-symbol-versions` does not
report symbol versions, despite the flag.

`readelf` should be a more reliable alternative which is also part of
binutils.

See https://github.com/spack/spack/issues/44534#issuecomment-2151796917
for more information
