Half of the ports had a manual post_install step to delete libtool files
this is now done automatically and there is no need for it!
Libtool files have to be deleted as libtool doesn't work while
cross-compiling (at least out of the box)
I've had this laying around locally for a while. binutils was not
working so I didn't feel like this was worth pushing. My new stdio FILE
buffering rewrite fixed binutils and now gcc actually works!
