[PATCH v2 03/11] tests/tcg: add concept of container_hosts

["Alex Bennée" <alex.bennee@linaro.org>]

While docker is nominally multarch these days it doesn't mean our
distros actually package all cross compilers for all architectures.
The upcoming Debian bullseye release will improve things further. At
least for now we can get things like the 32 bit ARM compiler on it's
64 bit cousin.
