[PATCH 3/7] tests/docker: Update debian-hexagon-cross to a newer toolchain

[Richard Henderson]

From: Brian Cain <brian.cain@gmail.com>

The new dockerfile uses a complete toolchain built by CodeLinaro.
Remove the special casing that was necessary when the dockerfile
built the toolchain from source.

Suggested-by: Brian Cain <bcain@quicinc.com>
Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
