to output the same QMAGIC format as BSDI does. This is triggered by
a new '-q' flag ('-Xlinker -q' in gcc). The default can be changed from
ZMAGIC to QMAGIC by defining DEFAULT_MAGIC=QMAGIC when building ld.
ld won't generate output if there are two .o files with the same
name. It thinks they are multiply defined external references. This
patch explictly allows multiple /file names/ with the same value.
This can happen if you do a two stage link or if you link in file
names that are identical to files in libc.
Otherwise ld.c exits with a status=1 and non error message. Rich
