[PATCH] read.c: Don't special case the set directive for COFF


assign_symbol contained special logic specifically for COFF which
would make a symbol specified in a set directive local by default.
Special casing this behavior for COFF doesn't seem warranted and makes
it so that non-external alias names _never_ show up in the symbol

The patch bellow changes assign_symbol so that it behaves just like
ELF in this respect.
