Subject: [PATCH] kconfig: allow ARCH set to 'the machine hardware name', like 's390x' but not 's390'

This patch add support for setting ARCH to 'the machine hardware
name'(`uname -m).

UTS_MACHINE is not always the same as SRCARCH, for example, s390x, we
should set UTS_MACHINE=s390x, and SRCARCH=s390. This patch makes that
working when "make ARCH=s390x".

And it avoid some error during invocation of make when ARCH set to
s390x, ppc64 or some machine hardware name else. Lots of scripts will
have no need to hack(like what we did in Red Hat), just use `uname -m`.
