Specifically, set '-mabi=XX' in AFLAGS, CFLAGS, and LDFLAGS. This permits building MIPS worlds and binaries with a toolchain whose default output does not match the desired TARGET_ARCH. _LDFLAGS (which is used with LD instead of with CC) required an update as LD does not accept the -mabi flags (so they must be stripped from LDFLAGS when generating _LDFLAGS). For bare uses of LD (rather than linking via CC), the desired ABI must be set by setting an explicit linker emulation as done in r316514 for kernels and kernel modules.
