How is this supposed to work?  Assume I have a number of different
tool chains, say I want to use the tool chain in /opt/eldk-5.1/armv5te
for all ARM9 systems, that in /opt/eldk-5.1/armv7a for all OMAP based
boards, that in /opt/eldk-5.1/armv6 for Kirkwood processors and yet
another one for the (bix endian) PXA boards.  In all cases we have
ARCH=arm and CROSS_COMPILE=arm-linux-gnueabi-

And then, for compatibility testings, I want to compile all this with
ELDK 4.2.  Or ELDK 4.1. Or CodeSourcery xxx. Or...

I see no clean way to implement this - ok, we could provide an
external tool / data base that maps boards or SoC names to
CROSS_COMPILE/ARCH/PATH settings, which each user has to configure for
his own set of tool chain settings.

Best regards,
