libgdiplus: fix cross-compilation error

Browse Source 
When cross-compiling with toolchains that validate things like headers
and libraries paths, we were getting errors like:

sh-linux-gnu-gcc: ERROR: unsafe header/library path used in
cross-compilation: '/lib'

That's because there was an error in the configure script that was not
generating ldflags correctly, and the generated Makefile was trying to
link with -L/lib.

Also, it is necessary to pass a prefix when compiling with libjpeg and
libtiff support.

A patch has already been sent upstream.

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.
