Bug#24925181 INCORRECT ISA DETECTION CODE IN OEL RPM SPEC

Wrapper for mysql_config used in multilib installs modified to work as
intended, added more archs (aarch64, ppc64le, s390x, s390, sparc and
sparc64) to lists in fallback mode and use same script for EL and
Fedora.

Thanks to Alexey Kopytov for report and fix.
