If something is annoying during a build, chances are it will also be
annoying in other circumstances, so rather than temporarily disabling
it to work around the problem, we'd rather make it work right.

Note that vc-bzr.el has its own implementation of a subset of "bzr
status" and it falls back on "bzr status" in some cases not covered by
its own code.  So it might be that the built-in code works fine for your
situation but not for the OP's.
