There are probably good reasons to put glibconfig.h there - hint: 
platform-dependent vs. platform-independent header files.  This is the same 
with qmodules.h and qconfig.h - those should *not* be in $PREFIX/include.
Otherwise, it becomes impossible to use --exec-prefix properly for installing 
software in a multi-platform NFS setup.

I doubt that.

I don't know what the "proper" solution is, but AFAICS, you *do* need two -I 
paths in CPPFLAGS.  The only alternative solution I see is a platform-depend 
include directory with *all* files duplicated (possibly symlinked).
