From aaafe69e282720f4e3685ffacfbb8a24644a289c Mon Sep 17 00:00:00 2001 From: Jonathan Gray Date: Fri, 24 Mar 2017 03:13:56 +0000 Subject: Add "supported targets" in lld --help output to be compatible with what libtool generated configure scripts expect. Otherwise they might assume shared libraries aren't supported. From lld svn revisions 298568 and 298571.
