Yea, we have no good way to prevent breakage for things like this short of
moving the changing
data into a file so dependencies can be tracked. I'm agnostic on the method.

I'm also not sure I know  of a good way to fix this short of doing a make
clean if any of the mips .o
files are present.

In removing mips, I'm generally uninterested in making sure no clean works
over that event because
it is a one-shot. But am happy to work with others that are interested to
mitigate the damage.
