I think MFLAGS is deprecated.  Is there a reason you use this instead of
MAKEFLAGS?

I did make the change on purpose, because the new -O flag with an
optional argument wasn't getting parsed correctly with the space (it was
being parsed as -O, which defaults to target sync mode, plus a goal
"none").

I didn't think it would affect anyone so I used the simplest solution,
of removing the space.

However, I can probably make it work the old way as well and revert that
change.
