Right now I'm in a panic mode just trying to get it to work.

Does the -print-sysroot work and return the correct path on your
non-multilib external toolchain?

I already have the "Target Architecture Variant" and the other options
set correctly.

BR2_arm=y
BR2_ARM_TYPE="ARM920T"
BR2_ARM_EABIT=y
BR2_ARCH="arm"
BR2_ENDIAN="LITTLE"
BR2_GCC_TARGET_TUNE="arm920t"
BR2_GCC_TARGET_ARCH="armv4t"
BR2_GCC_TARGET_ABI="aapcs-linux"

I'm still trying to get it to work but I'm a bit lost.  There are still
a bunch of things about makefiles and all the shell stuff in them that
I just don't get ;-).

The main problem I am having is modifying ext-tool.mk correctly.

If you have the time I would appreciate any help.  I can test anything
that you might suggest.

Thanks,
Hartley
