Cross-compiler or not, the pkg-config files only work correctly for a

Since the pkg-config files are only created at "make install.libs", we
currently need to install the library into a temporary location. I've
come up with the following patch:

Only tested that "debian/rules build-test" works in a native build, will
need to check full native and cross builds later on.
