Subject: [PATCH] Fix %postun scriptlet for llvm-devel when
 upgrading/downgrading

The scriptlet tried to run llvm-config-%{maj_ver} when upgrading or
downgrading to check if ${maj_ver} has changed. Since postun runs
after the package files have been uninstalled this will always fail
to run the command. We should run instead llvm-config%{exec_suffix},
which in the case of upgrades or downgrades will still be present,
installed from the new package.
