conditional assignment problem

[Krzysztof Horecki]

Hi, everybody:

I wanted to implement some sort of variable override, but...

I have some definitions:

HOST_TYPE=LINUX

ARCH=arch_common
ARCH_LINUX=arch_linux

and a conditonal assignment:

ARCH_LINUX ?= $(ARCH)

test:   
        @echo $(ARCH_$(HOST_TYPE))

as soon as I remove ARCH_LINUX definiton it doesn't work. Seems that
make does not like variables on the right side of the conditional
assignment. Any ideas how to do it without conditionals?
