A while back I was looking to do the same thing (assemble macro11 files into 
.bin images loadable into, for example, simh) but never found a solution like 
the sources for a linker outside of a DEC O/S.

So I built this: https://github.com/AK6DN/obj2bin

And use it like this in my Makefile (under cygwin on windows):

    *# makefile for pdp11 bin code**
    **
    **.PRECIOUS: %.obj**
    **
    **MACOPT ?= -d md -d me -e bex -yus -rt11**
    **OBJOPT ?= --debug --verbose**
    **
    **%.obj : %.mac**
    **    macro11 $< $(MACOPT) -l $*.lst -o $@**
    **
    **%.bin : %.obj**
    **    obj2bin.pl $(OBJOPT) --binary --log $(@:.bin=.log) --out $@ $+**
    **
    **# all the files to be made**
    **BIN=memx.bin echo1.bin echo2.bin dl11.bin**
    **
    **all : $(BIN)**
    *

Besides linking multiple .obj into a single .bin, it can also generate M9312 
compatible boot and console PROM hex image files.
