[PATCH 4/4] Some extra --combine hacks.

[David Woodhouse <dwmw2@infradead.org>]

Do not apply. Mostly just Makefile hacks to make --combine get used by
using multi-obj compilation in a few places. The correct fix is to use
--combine properly for all C files in built-in.o

We do start to see interesting reductions in size in net/*/built-in.o
when we do this, though...
