commit 9e417a6e6c96ec63d3085e3d2dfd147c0a169a4e Author: Martin Roth martinroth@google.com Date: Sat Aug 22 10:37:39 2015 -0600
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.
