On top of the previous biarch changes for UML, this makes the preprocessor
changes a bit cleaner. Specify the 64-bit build in CPPFLAGS on the x86_64
SUBARCH, rather than #undef'ing i386. Compile-tested with i386 and x86_64
SUBARCHs.

I run an x86_64 kernel with i386 userspace (Ubuntu Dapper) and decided to try
out UML today. I found that UML wasn't quite aware of biarch compilers (which
Ubuntu i386 ships). A fix similar to what was done for x86_64 should probably
be committed (see
http://marc.theaimsgroup.com/?l=linux-kernel&m=113425940204010&w=2). Without
the FLAGS changes, the build will fail at a number of places and without the
LINK change, the final link will fail.
