Cross-compiling is a special case that you need to make lots of
preparations to deal with. pkg-config will not magically solve your
problem.

For dynamic libraries, this is automatically taken care of. For
archive (static) libraries, one solution (perhaps the most proper for
strange dependencies) is including one archive inside the other.
However, for most common libraries, the dependencies are _known_ by
the program using the library, e.g. libpng's dependence on libz.

Seriously, this all worked fine for the past 7 years or so before
there was such a thing as pkg-config. pkg-config is yet another case
of overengineering and inventing a solution to a nonexistant problem,
or rather inventing the problem itself, which seems to be a common
mistake of GNU/Linux these days and leads to endless bloat...
