But if, as I suggest, we're doing the simple option which combines only
the files which tend to get most benefit from it -- those which are in
the same directory -- then there's not a lot of point in the separate
target. It really doesn't take that much extra time.

I thought that it used rather a lot more RAM. I still often(ish) compile a kernel on my PII/300/128M. It'd be moderately annoying if it got slower, and there was no way to turn it off.
