When building against non-local, non-disk-backed file systems (e.g. NFS, tmpfs), the u-boot build can iterate forever, attempting to re-generate "include/autoconf.mk". This occurs because $(VERSION_FILE) (aka ${ROOT}/u-boot/build/include/version_autogenerated.h) is always regarded as out-of-date because it is in the .PHONY target list, even though it's a real file and seems to need to be only created once and only once.
This patch removes $(VERSION_FILE) from the .PHONY target list and has been verified to work with various flavors and builds of make-3.81 against NFS, ext2fs, ext3fs and tmpfs file systems.

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.
Wolfgang,
This patch works effectively and successfully when tested against NFSv3, EXT2, EXT3 and TMPFS file systems with make v3.79, v.3.80 and v3.81.
Thanks,
Grant
