 libpayload should have a gcc wrapper script which simplifies compilation
 of libpayload-based payloads a lot. From a user's (payload writer's)
 perspective compiling a payload should be as simple as replacing "CC=gcc"
 with "CC=lpgcc" in the Makefile, everything else should be handled by the
 script (include paths, linker options, etc).
