From cb97fd7741fc8bfa257bb020dab756a14c420daf Mon Sep 17 00:00:00 2001 From: Michael Hudson-Doyle Date: Fri, 29 Apr 2016 10:37:37 +1200 Subject: [PATCH] cmd/link: fix -no-pie / -race check golang.org/cl/22453 was supposed to pass -no-pie to the linker when linking a race-enabled binary if the host toolchain supports it. But I bungled the supported check as I forgot to pass -c to the host compiler so it tried to compile a 0 byte .c file into an executable, which will never work. Fix it to pass -c as it should have all along.
