That's not a problem - that's standard practice even on the native 
builds of those packages. The config.h files here contain various
macros / defines that are variable according to the build host. By
putting them in the lib directory, you can have -devel packages for
both 32-bit and 64-bit versions installed in parallel & get the correct
definitions. Now this isn't important to MinGW since we only target
Win32, but there's no need to move them.
