[U-Boot] setting of ARCH based on HOSTARCH?

[Kumar Gala]

Wolfgang,

I've been building for sometime now on a native PPC box w/o any  
issue.  However in looking at the Kconfig patches it showed in an  
issue in that I don't ever set ARCH to anything.  It seems like there  
are two solutions to this:

1. ARCH is expected to be set explicitly be the user
2. add something like:

ifndef ARCH
ARCH = $(HOSTARCH)
endif

into the toplevel Makefile.

Feelings?
