Summary:
Work on adding -rpath support to the mach-o linker.
This patch is based on the ld64 behavior for the command line option validation.
It includes a basic test to check that the LC_RPATH load commands are properly generated when that option is used.
It also add LC_RPATH support to the binary reader, but I don't know how to test it though.
