This is due to auxinfo.h becoming a prerequisite after the first
build recorded the dependency.
D'oh, of course I only tried to run "make" once when testing that patch :-/

There are two instances of the %.aux.o target in arm/Makefile.common. We
need to fix both. We can actually pull the target out of the two arms of
the CONFIG_EFI if-else, though, by changing the .efi/.flat to .$(exe).
I went ahead and pushed this patch with the trivial fix for the else-branch
to the repo to unbreak the build. If you think it's worthwhile to unify the
target, please provide a patch to do so, thanks!
