Why not:

$ RC_ARCHS="x86" make
echo Apple Build.
Apple Build.
$ make
echo Standard Build
Standard Build
$ cat Makefile
ifneq ($(RC_ARCHS),)
include Makefile.apple
else
all:
	echo Standard Build
endif
mrs $ cat Makefile.apple
all:
	echo Apple Build.

It leaves Makefile mostly alone, all except for three lines at the top  
and one line at the end of it.
