-Subject: [PATCH] Pass LD_GOLD=1 via makefile to enable gold linker
-
-Current logic prefers gold if a toolchain has gold linker installed and
-does not offer any option to chose default linker which might not be
-gold linker. Its better to pass this control to user instead of auto
-detecting and deciding.
