Closer to the original problem, if you are doing a cross compile
build and there is no cross pkg-config but the native pkg-config
exists and finds the native version of the library, you will get
build errors at the linking stage.

These link stage errors can be difficult for people who are new
to cross compiling to debug and fix. They are also difficult for
people who do lots of cross compiling but are new to software
using the autotools.
