That's cool :-)

Basically this

+ifneq ($(SUBARCH),$(ARCH))
+       ifeq ($(CROSS_COMPILE),)
+               CROSS_COMPILE := $(call cc-cross-prefix, hppa$(WIDTH)-linux- hppa$(WIDTH)-linux-gnu-)
+       endif
 endif

should then be enough.

Do we really need to search for: 
	hppa1.1-unknown-linux-gnu
	hppa1.1-linux-gnu
	hppa1.1-linux
	hppa2.0-unknown-linux-gnu
	hppa2.0-linux-gnu
	hppa2.0-linux
on 32bit?
