This patch includes some corrections to makefiles and adds a script to be used when crosscompiling.
In particular, I introduced the option to specify the cross toolchain prefix, static linking and stripping
the binaries and specify eventually another jpeg library directory to be used instead of the current one.
./cross-compile.sh --help to have some help about.
