[coreboot-gerrit] Patch merged into coreboot/master: d69839b build system: use full (in-tree) paths

the following patch was just integrated into master:
commit d69839bdfdea5d67bbbed12f29cdac52e9036875
Author: Patrick Georgi 
Date:   Fri Apr 3 10:32:17 2015 +0200

build system: use full (in-tree) paths

So far we assumed that all files in *-srcs are below src/
    which wasn't really true actually and will be less true with
    future changes.

Fix up crt0.S handling on x86, which is covered by default rules
    due to this change.

This is inspired by the commit listed below, but rewritten to match
    upstream, and split in smaller pieces to keep intent clear.
