[PATCH 1/4] build: fix missing x86-specific help output

[Andres Salomon <dilinger@queued.net>]

Normally 'make help' spits out architecture-specific targets (including
things like foo_defconfig).  However, it looks like ARCH was never changed
to SRCARCH during the x86 transition; the makefile still looks in
arch/i386/configs for arch-specific config files (if ARCH is i386, that is).

This changes it to use SRCARCH, which makes it properly display things
like i386_defconfig and x86_64_defconfig.
