gccld -disable-opt on 252.eon.
This patch deletes it and replaces it with a map. The proper fix for this
is to fix PR411, but this will do in the short term.
gccld on eon now takes 5.51s, which is 50% faster than before this patch. :)

Do not call FindGlobalNamed when we know we will ignore the result (because
we are not going to link a static symbol anyway). This speeds up
gccld -disable-opt on 252.eon from 8.63s to 8.39s.
