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.
