still, it seems kind of weird, there are rpmlint checks for unstripped
libraries, but i do have 34 libraries not marked as executable, while the
stripping+ debug seems to target only executables?
i wonder if we should make another check library unset as executable or even
check what happened with these libraries not marked as executable?
