Man. If only the multi-libs and crosses were built with staged includes
and libraries... a lot of this Irix hackery would be greatly simplified.

Um. Isn't 'make check-abi' only useful for systems that are actually
using versioning, like BSD and Linux? I'm not aware of other platforms
that actually are using symbol versioning. 

Perhaps it is useful, but that was not the intention of this Makefile

Must be missing something,
