Could you forward those to me?

I guess download.sh also comes from Willy?

Ack.

Could you provide a transcript of the commands you are running and their
outputs, including the failing command?
>From the error it looks like run-tests.sh is the one failing, but that
script was written completely oblivious to download.sh and
TOOLCHAIN_BASE, so those probably won't help solving the issue.

The following command should automatically download the toolchains into
the location from the error message:

./run-tests.sh -p -m user

These toolchains can then also be used for direct "make" invocations
through CROSS_COMPILE.


As Willy said, thanks for the report!
