+Subject: [PATCH] Makefile: avoid calling sync
+
+Original commit message:
+Makefile: use ld-gold if it is available
+
+Speed up linking by using ld-gold if is available. Add build
+time detection to see if compiler allows it
+
+MJ: backported only the "sync" removal from Makefile as calling
+    it from do_compile in the middle of big OE world build harms
+    the build time.
+
+Upstream-Status: Backport [V0.14.04 c10e5c3f9f5560a085279f4c4b399c2f34cb897d]
