Good point.
That is a rare case that Kbuild cannot handle.

One idea is to make if_changed to write the command to *.cmd.tmp
and rename it to *.cmd after everything succeeds.
So, it is a similar approach, but the difference is that
it is done in the Kbuild core scripts instead of every command.
I will consider it.
