Subject: [PATCH 1/1] Fix compile error when cross-compiling.

When cross-compiling with libjpeg enabled, we can get errors like the

following when linking:

sh-linux-gnu-gcc: ERROR: unsafe header/library path used in

cross-compilation: '/lib'

That's because there is an error in the configure script that are not

generating ldflags correctly, and are trying to link with -L/lib.
