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.
