The details has long escaped me but in general we do not want to
have a job deleting all .o files running in parallel with a job that
creates .o files.

So we wanted the following to work:

	$make mrproper defconfig

make would in the standard configuration execute "mrproper" and "defconfig"
in parallel which would result in a broken build.

This is the background for some of the ugly hacks in the
top-level makefile.
