fails when using "hppa2.0-xxx".  perhaps:
CROSS_COMPILE ?= $(shell $(CC) -dumpmachine | sed
's/^hppa[^-]*-/hppa64-/')

don't even need the ifeq check then

How is that different from Carlos' suggestion?

sorry, but i'm not seeing any e-mails from Carlos in this thread.  what is his 
suggestion ?

The reason it doesn't work is the same ... CROSS_COMPILE is defined to be
empty.

my suggestion was purely an incremental improvement on the patch you posted.  
it improves two things:
	- detection when the default tuple is hppa2.0-xxx rather than hppa-xxx
	- one line for set-variable-only-when-its-unset rather than three lines
