i think this is a bit misleading
because this doesnt result in working pkgconfig for cross compiling
you just get
WARNING: /usr/powerpc-linux-gnu/bin/pkg-config not found, library detection may fail.

now if you write a /usr/powerpc-linux-gnu/bin/pkg-config wraper
script then this would set PKG_CONFIG_LIBDIR already
the faq should explain the need for such wraper script and how to
write one, or configure should work automatically with the non cross
pkgconfig. that is unless theres a easier way to get pkg config to
work for cross compiling.
