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 spack/spack#44534 (comment)
for more information
