[coreboot-gerrit] Patch merged into coreboot/master: 990e7c9 build system x86: deprecate bootblock_lds and ldscripts variables

the following patch was just integrated into master:
commit 990e7c90f035f0c9363e0c65100373795758a1da
Author: Patrick Georgi 
Date:   Fri Apr 3 10:47:15 2015 +0200

build system x86: deprecate bootblock_lds and ldscripts variables

Instead of keeping this separate variable around, add linker scripts
    to the $(class)-y source lists and let the build system sort things out.

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