Unfortunately, last time I checked, the ELDK toolchains did not support
the --sysroot option, which is mandatory to use a given toolchain as an
external toolchain in Buildroot. We have tried to support non
sysroot-capable toolchains, but it was the source of various issues,
and since sysroot is now quite ancient and available in most
toolchains, it sounded like a reasonable tradeoff.

I wanted to, but I never understood how to get just the ELDK toolchain
and not a complete distribution. I'll try to see if I can test this
toolchain, but if you have some simple setup instructions to get just
the toolchain, that would be great.

Thanks,

Thomas
