[PATCH] build: disable container-based cross compilers by default

[Paolo Bonzini]

Container-based cross compilers have some issues which were overlooked
when they were only used for TCG tests, but are more visible since
firmware builds try to use them:

- Downloading and building containers as part of make adds a
  very long task to the build, unless you are on a fast network.
  Container images can be hundreds of MBs.

- Verbose progress information from the container builds
  is printed on stderr and messes up other output from
  make/ninja

- There seem to be some rough edges around failure too.

So, make container builds opt-in.
