[Buildroot] [PATCH v5 03/13] support/test-pkg: calculate toolchain name only once

[Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be>]

From: "Yann E. MORIN" <yann.morin.1998@free.fr>

The toolchain name was calculated in main() for reporting to the user,
and again in build_one() for creating the build directory. Calculate
it only once, in main(), and pass the build directory as an argument
to build_one().

I'm not sure why the mkdir is also moved up to main() - IMO, it fits
better in build_one(). Yann, the original commit message was just
"create build dir from caller", any reason _why_ you did that?

Changes v4 -> v5 by Arnout:
  - Reword commit message
  - Reorder patch series
