commit aa8b0520ecdd5762577605013a7f6a4867404180 Author: Patrick Georgi pgeorgi@chromium.org Date: Sat Apr 4 15:50:20 2015 +0200
build system: run linker scripts through the preprocessor
This allows combining and simplifying linker scripts.
This is inspired by the commit listed below, but rewritten to match upstream, and split in smaller pieces to keep intent clear.
