[PATCH v3 01/15] tests/tcg: Add docker_as and docker_ld cmds

[Bastian Koppelmann <kbastian@mail.uni-paderborn.de>]

At least for the TriCore target no easily available c compiler exists.
Thus we need to rely on "as" and "ld". This allows us to run them
through the docker image as well as with locally installed tools.
