Summary: `arch` doesn't behave in makefile definition

Running under sunos 4.0.3, I have the following in my makefile:

__________________________________________________________________
DEST          = $(HOME)/astrobin/`arch`
...
install:        $(PROGRAM)
	@echo Installing $(PROGRAM) in $(DEST)
	@install -s -g wheel $(PROGRAM) $(DEST)
__________________________________________________________________

And this works as expected when I type "make install":  I get my
program installed in /a/jjk/astrobin/sun3 (if on a sun3).  Note that
this works if the program is made and I only want to install.

However, with the following fragment in place:

__________________________________________________________________
LIBS          = $(HOME)/astro/astro.a \
                $(HOME)/util/util.a \
                $(HOME)/iraf/lib/`arch`/iraf.a \
                /iraf/local/bin.$(FLOAT_OPTION)/libimfort.a \
                /iraf/local/bin.$(FLOAT_OPTION)/libsys.a \
                /iraf/local/bin.$(FLOAT_OPTION)/libvops.a \
                /iraf/local/unix/bin.mc68020/libos.a \
                /usr/lib/libF77.a /usr/lib/libI77.a \
                /usr/lib/libm.a
...
__________________________________________________________________

I get the following error message when I try to make my program:

make: Fatal error: Don't know how to make target `/a/jjk/iraf/lib/`arch`/iraf.a'

Obviously, the `arch` works as expected in the DEST definition, but is
not getting read properly in the LIBS definition.  Can someone please
help me with this?

Thanks
