bitstream: Add tempoary workaround for build

The build process expects a bitstream in some cases and provides it in the
TOPDIR.  We don't want to just set a default, because if it's not provided
it should not be expected.

Once the generic machines become 'firmware-less', this workaround should be
removed.
