Yes.

arm/Makefile create the directory asm-arm and use it for the symlink.
But now asm is no longer a symlink to asm-arm so we fail.

I need to work out something.
But my first attemps failed miserably and I will stop for now
as I have some day-time job stuff to be done.
Travelling for a few days from now one so I cannot do anything
until the weekend.

Either we should pull the offending commit from -next or drop
kbuild-next.git.

As a sidenote I expect arm to benefit of the offending patch as we
could kill the symlinks when the header files were rearranged.
But that does not help us here.

As for sh and avr they both play symlinks games too - so same story there.
