[U-Boot] [PATCH] HACK: DO NOT MERGE: Simple program to printout preprocessed values

[Tom Rini]

When migrating to Kconfig there may be cases where the symbol to be
migrated depends on a preprocessed or calculated value, and thus
moveconfig.py will not migrate it correctly.  Introduce an easily
hackable tool, tools/printvars.c that will give the final value.  Hack
the main Makefile to only build this tool, and buildman to save this
tool.  Thus it becomes "quick" to have buildman build this tool for
every board in U-Boot today.
