From 626edf58df45b87eb590627b71436aafaa3624b5 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Wed, 24 May 2017 09:05:29 +0200 Subject: Makefile: Speed up evaluation of ld options Since "333ff7b1e4 Fix linking with new ld, based on u-boot" the build with multiple images became unreasonable slow. This is because the ld-option macro was evaluated once for each image. Fix this by exporting and using LDFLAGS_barebox from the main Makefile.
