Subject: [PATCH] kbuild: include localarch for simple cross overrides

For people banging on kernel trees which are dedicated to a specific arch,
it'd be nice to allow the repo itself to declare the default ARCH (and
CROSS_COMPILE) easily.  Just like the "localversion-*" files, people can
just do:
echo 'ARCH ?= blackfin' > localarch
and the tree will default to 'blackfin' all the time rather than whatever
the build machine happens to be.
