This would just replace my wrapper script with a binary which is not
really a better solution :-).

Hmm, I'm not sure this is really the solution either.

What I am suggesting is a single pkg-config binary which works
for both native compiles like it does now, but also work for
cross compiling using a --host argument (in my current case
i586-mingw32msvc).

Give the --host argument, pkg-config would then override both
PKG_CONFIG_LIBDIR and the users own PKG_CONFIG_PATH variable.

I've also just found this:

However, thinking about this some more, I'm beginning to think
that my wrapper script is actually a better solution.
