[PATCH] uml: start cross-build support : mk_user_constants
Beginning of cross-build fixes. Instead of expecting that mk_user_constants
(compiled and executed on the build box) will see the sizeof, etc. for target
box, we do what every architecture already does for asm-offsets. Namely, have
user-offsets.c compiled *for* *target* into user-offsets.s and sed it into the
header with relevant constants. We don't need to reinvent any wheels - all
tools are already there.
This patch deals with mk_user_constants. It doesn't assume any relationship
between target and build environment anymore - we pick all defines we need
from user-offsets.h. Later patches will deal with the rest of mk_... helpers
in the same way.
