[U-Boot] [PATCH 1/2] Don't let the command-line ARCH=powerpc override our redefinition to ppc.

[Scott Wood]

The override keyword is needed for make to take our version over the one
specified on the command line, and remove it from the list of command line
overrides that are passed to submakes.  IMHO, the combination of "export"
and "override" ought to do this automatically, but oh well.
