Problem detecting Libs with gcc-fat.sh

Hello !

I have the problem that when using gcc-fat.sh
./configure is not able to detect correctly
if a lib is installed or not. For example
the detection of SDL fails, because configure
can not find SDLmain. Also it is not able to find
for example libPNG, libJPEG and so on.

All the libs are correctly installed and all of them
are Universal ones, i checked that with LIPO.

When building the normal way for me using PowerPC with
just ./configure everything works correctly.
