You do not need to build kdelibs in general - you can use the one from your 
distribution.
The same goes for uic, too.

Of course, you can build both on your own, but I doubt kdelibs would compile 
without tweaks against qt-embedded.

Just be sure to have your regular uic and dcopidl binaries in your PATH 
before any of the cross-compiler stuff.
Or you can copy over the x86 files to your cross-compiler environment.

./configure --qt-mt should do.

I keep QTDIR unset normally, you may want to set --with-qt-includes=
and --with-qt-libraries= to force the use of your cross-compiled libraries.
