Nope, to absorb pkg-config libtool will need to be aware of .pc files too.
If libtool can't find a .la file, but there is a suitable .pc file in the
search patch, libtool would pull the flags from there.

A good idea!

But linking against installed libraries using the correct -L and -l flags
*is* part of portably building/using libraries! ;-)

Haven't thought through the -I thing yet though... maybe that doesn't
belong in libtool... maybe we could provide a macro that can intuit
include directories from .la locations... I dunno...
