Partial revert "cross compile with mingw": unbreak pkg-config

This partially reverts commit
07a978d3d4b41739eff1061dc45dbfa737bf78b9.

Despite what the commit message said, pkg-config previously worked
and was useful, particularly for static Qt. Qt itself even installs
its own .pc files.

Note: The mkspec win32-g++-cross had a PKG_CONFIG definition to avoid
using the pkg-config installation on the build machine.
