I haven't monkeyed with this  too much (and not  at all on a 3b15 that
you said you're on), but the version of "ld" that reads arguments from
a file is probably called  "ld" on your system  (small joke).  Really,
though,  the standard SVR2 "ld" can  use something  called an "ifile".
The  "ifiles"  (anything not  an archive or   an object)  contain "ld"
directives.  Among other things, generally anything that you could put
on the "ld" command line qualifies as a directive.  E.g.,

	ld -x -y a.o b.o c.a

is the same as

	ld eye.file

where "eye.file" contains:

	-x
	-y
	a.o
	b.o
	c.a

I don't know if  this is going to solve  your problem with overflowing
tables, though.  (That  doesn't mean  "I  doubt it";  it just means  I
dunno.)  Another possibility (somewhat  more effort) is to do  several
loads hierarchically.   The  early ld's generate  relocatable  outputs
which  are part of the  next load.  The hope  is  that you resolve and
submerge some of the symbols along the way.
