Please do not run "mrproper" with "*_defconfig" and "all".


Doing "_defconfig" and "all" at one time is supported,
but you must "clean" or "mrproper" separately.
This is the upstream limitation.  Linux Kernel does not support it either.


Without -j* option,  "make mrproper  *_defconfig  all" works, of course,
because they are run one by one in the given order.

With -j* option, it would not work because
the build system removes some files while it compiles other objects.

I guess this is the root cause of the inconsistent fails you have seen.
