[U-Boot] [PATCH] config.mk: enable -fstack-usage only when it is desired

Hello Tom.

OK. This works.

But I'm kind of afraid ifneq($(CONFIG_M68K)$(CONFIG_...),y) ... endif
might be too arch-specific to be written in the top config.mk.

Instead, we can add
CONFIG_CC_STACKUSAGE=y
to arch/{arm, powerpc, x86, microblaze ...}/config.mk
