Hi Masahiro > > Kbuild does not cater to the mixture of clean targets and build targets, > but I do not know why. 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.
