[PATCH] uml: Set cflags before including arch Makefile

[PATCH] uml: Set cflags before including arch Makefile

If arch/$(ARCH)/Makefile is included before adding -O2 (and the rest) to
CFLAGS, I must duplicate the addition of it to USER_CFLAGS for UML.  So let's
fix this.  Also, the below code is useless, since if CONFIG_DEBUG_INFO is y,
then CONFIG_FRAME_POINTER is always y.

ifeq ($(CONFIG_DEBUG_INFO),y)
CFLAGS := $(subst -fomit-frame-pointer,,$(CFLAGS))
endif
