Is that really what's required here, though?

I would have thought that if the cleandir command completed before the
rest was executed would have been sufficient, since most of the action
here happens in subdirs, presumably in separate make processes?

BTW, in the August 1 autobuild results, 15 of the 34 failed builds
failed because a parallel cleandir interfered with the configure phase
for some of the tools.

I'm on thin ice here, I know, but would it help making the above
command sequence (plus the missing "echo ${TOOLDIR} >PREVIOUSTOOLDIR")
a separate target, and putting a .WAIT after it help in any way?  Such
as...

Trying to reproduce this problem on a single-CPU system appears to be
difficult.  Either that or my test machine is too slow.
