From b25a577fda06482d68f6af7b54995c1c417f43e0 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Wed, 10 Jan 2018 15:12:47 -0800 Subject: [PATCH] Makefile: Use ld.bfd linker if available Some toolchain distributions install both the BFD and GOLD linkers under the names -ld.bfd and -ld.gold. -ld will then be a symlink that may point to either one of these. Trusted Firmware should always be linked with the BFD linker, since GOLD is meant primarily for userspace programs and doesn't support many of the more obscure linker script features that may be needed for firmware. With this patch the Makefile will auto-detect if ld.bfd is available and use it explicitly in that case.
