Author: blueswirl Date: Sat Feb 16 13:08:33 2013 New Revision: 1099 URL: http://tracker.coreboot.org/trac/openbios/changeset/1099
Log: build: support disjoint build directory
Support building in any directory, not just in-tree build.
Use VPATH for non-Forth files.
Forth compiler does not support explicit paths, so drop source path prefixes added by XML and rely on directories passed with -I flag.
