I think your plan as posted on the patch list is a good start.

I always liked the gcc-style names like `CC_FOR_BUILD',
`CFLAGS_FOR_BUILD'; they always seemed the easiest to understand.
(Other folks have suggested BUILD_CC, BUILD_CFLAGS, etc.  Which,
really, aren't that much harder.)

Having a `build_' prefix for primaries makes sense to me.

For autoconf it would be nice if you could tell it "now I want to do
checks on the host compiler" and have it change the definition of CC
(and other flags), have a new build-specific config.h, etc.  The
required changes might be extensive.

I agree with Alexandre that we don't have to support target, just host
and build.  Well, really it might be nice to clean up target library
support, but I wouldn't recommend it unless you have a real need; it
is pretty messy.
