Makefile: Allow arch post-link hook

This commit allows an architecture to provide a Makefile.postlink whose
u-boot target gets invoked after the u-boot ELF is linked. This will be
of use for MIPS in a following commit.

This mirrors Linux commit fbe6e37dab97 ("kbuild: add arch specific
post-link Makefile").
