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.
