Patch merged into coreboot/master: cedbdcd lint: Get absolute path in compare_output

the following patch was just integrated into master: commit cedbdcdae7f045dc2b69da8b224298f70254db35 Author: Zheng Bao <fishbaozi(a)gmail.com> Date: Fri Sep 28 20:14:38 2012 +0800 lint: Get absolute path in compare_output The classes in $(top)/Makefile uses $(abspath) to get the path. The $(abspath) can not resolve symlink. If the coreboot is located in a symlink directory, the run_printall produces the absolute path while the $PWD just produces the path with symlink. Use `pwd -P` to get the abs path.
