Patchwork [1/1] insane.bbclass: add library dir sanity check

Check in ${PKGD} for libraries in wrong locations.
Trigger a warning if so.
Eg. Catch recipe installing /lib/bar.so when ${base_libdir}="lib32"
or installing in /usr/lib64 when ${libdir}="/usr/lib"

[Yocto #2038]

I merged this but added a follow up with one other tweak since this
wouldn't work in the case libdir was in ERROR_QA:

http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=30b7781650e3ff092d04889beab2e87eaff29cdb

I had some other cleanup in mind so I wrote the patch as that was the
easiest way to explain it :)

Cheers,
