From 8047d058766d875040580337e2e818a32a1a314b Mon Sep 17 00:00:00 2001 From: Shenghou Ma Date: Wed, 23 May 2012 11:36:24 +0800 Subject: cmd/ld: fix Linux/ARM build CL 5823055 removed a line introduced in Linux/ARM cgo support. Because readsym() now returns nil for "$a", "$d" mapping symbols, no matter the settings of `needSym', we still have to guard against them in ldelf().
