KDE CMake files cannot support mutiple ABI

[Miguel Marte]

This is all in gentoo with native multilib support.  All 64bit libs
are installed to /usr/lib64.  All 32bit libs are installed in
/usr/lib32.  /usr/lib is a symlink to /usr/lib64.   The prefix for
both is the same from what i remember.  It is /usr.  All other
packages are building correctly, both for 32bit and 64bit, including
phonon.  Its just the packages that use the cmake files from KDE as
far as I can tell.
