add framework for arch-provided makefile fragments, compat source dirs

the immediate usage case for this is to let 32-bit archs moving to
64-bit time_t via symbol redirection pull in wrapper shims that
provide the old symbol names. in the future it may be used for other
types of compatibility-only source files that are not relevant to all
archs.
