This may fix your immediate problem, but it is wrong. Assume you have
built U-Boot from some specific version, then the git commit ID  will
be  shown  as  part of the version string. Assume you now edit a file
and run "make" again. The intention is that this new build shows  the
"-dirty" marker in the version string, plus the new build date.

Your change breaks this behaviour.

I just  posted  another  patch:  ``Avoid  infinite  loop  "Generating
include/autoconf.mk" '' which is supposed to fix the problem, without
unwanted side effects.

Please test.

Best regards,

Wolfgang Denk
