Another classic way is the use of a CROSS_COMPILE variable.
The Makefile then looks something like this:
CC=$(CROSS_COMPILE)gcc
AR=$(CROSS_COMPILE)ar
...

By just setting CROSS_COMPILE to e.g. "mips-linux-uclibc-" you can do
cross compilation while not setting the variable uses your host
compiler (provided your toolchains are appropriately named).

In any case, adding ARFLAGS is certainly useful.
