configure: Adjust READELF_REGEXP for OpenSuse

Leap readelf verion looks like:
GNU readelf (GNU Binutils; SUSE Linux Enterprise 15) 2.43.1.20240828-150100.7.49
Tumbleweed uses:
GNU readelf (GNU Binutils; openSUSE Tumbleweed) 2.43.1.20240828-2

So also allow ';' and numbers before the actual version.
