i think you'll need to split this up in logical sep changesets since you are 
fixing different problems.

i dont like copying & pasting the same logic in multiple places.  this is how 
code rots and bug fixes diverge.

considering LDSCRIPT/CONFIG_SYS_LDSCRIPT only get used by the top level u-boot 
file, and only when the system is configured, i wonder if we shouldnt just rip 
it out of config.mk and into the top level Makefile.

let's see what Scott thinks ...

the VERSION_FILE changes look fine

pretty sure this breaks board builds.  if the only thing this fixes is a 
harmless warning when generating dependency files, then i say ignore it.  
after all, this is how it has always worked in the past and no one really 
cared.
