pass const empty string to MAKEEXTRALIST macro instead of the
anonymous empty string. the macro uses the argument multiple times
and the logic relies on identical strings having the same address,
which is compiler dependent and not guaranteed to be the case.
problem observed with pax(1) built with sunpro 11 on Solaris.
from segv@netctl.net in PR pkg/32097.
