From dbb50c48f9f40f2f4d7960096f6b5462bfb3a39c Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Sat, 22 Aug 2015 10:37:39 -0600 Subject: x86: Get rid of empty loadable segment warning When the check for global symbols in romstage happens, if everything is good, a warning appears, telling us that the segment is empty. While the empty segment is good, the warning is distracting: "BFD: build/cbfs/fallback/romstage_null.debug: warning: Empty loadable segment detected, is this intentional ?" This change hides that particular warning, but shouldn't hide any other output from objcopy.
