OK, so as I see it, this is not a race but a dependency problem: the 
"tools-only" target just does not generate the "generic-asm-offsets.h" file.

However, just adding a dependency to 
include/generated/generic-asm-offsets.h leads to an error (no rule to 
build that file) since that file is generated by Kbuild magic that I 
don't really get...

Any idea how to make this depend on /Kbuild being run?
