[PATCH] uml: fix compilation options for USER_OBJS
From: Jeff Dike <jdike@addtoit.com>, Paolo Giarrusso <blaisorblade@yahoo.it>
Make sure that when compiling USER_OBJS the correct compilation options are
passed; since they are compiled with USER_CFLAGS which is derived from
CFLAGS, make sure it is a recursively evaluated variable, so that changes
to CFLAGS done afterwards the inclusion of arch/$(ARCH)/Makefile are
reflected in USER_CFLAGS.
For instance, without this patch userspace objects are never compiled with
debug info active.
