>Description:
setmode(3) doesnt work correctly for file modes with 'u', 'g' or 'o' on the
rhs of an '=', for example go=u-w.

>How-To-Repeat:
	Try chmod go=u-w file
>Fix:
The bug was introduced recently by a change to src/lib/libc/gen/setmode.c
(see diffs). I couldnt figure out why that change was made, but undoing it
would fix this problem (and perhaps cause others ??)
