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?
