commit 22add2b8d5b88de896efc58a8a819c68e4dce84d Author: Patrick Georgi pgeorgi@chromium.org 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.
