Subject: [PATCH] Move the architecture guessing from Makefile.inc1 to
 Makefile.  We need to do this because variables specified on the command line
 override those specified in the Makefile.  This is why we also moved from
 TARGET to _TARGET in Makefile, and then set TARGET on the command line when
 we fork a submake with Makefile.inc1.

This makes mips/mips work again, even without the workaround committed to
lib/libc/Makefile.
