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.
