Bug#36086236 Enable and use correct toolset for rpm builds on el* platforms

Bug#36054662 With PGO enabled, build fails to produce commercial-debuginfo RPM on EL8
Bug#36072667 EL8 RPM "libmysqlclient.a" exports no symbols

strip and dwz from /usr/bin used by rpmbuild might break object files
and binaries produced by GCC Toolset on el* platforms.

See for example:
 https://sourceware.org/bugzilla/show_bug.cgi?id=24195

Point to newer strip and make sure corresponding dwz tool is available
(set $PATH correctly to let script use it).

Post processing in rpmbuild by brp_strip_static_archive runs "strip
-g" which breaks static archive on el8 even if newer strip is used,
disable this processing completely.
