strange Makefile generation for readline under NeXTStep

[Leigh Smith <leigh@antechinus.cs.uwa.oz.au>]

I'm not sure if this is NeXTStep specific, but running

./configure --prefix=/usr/local  $(ARCHDIR)
./makemake  --prefix=/usr/local --disable-nls --with-readline  
--with-dynamic-ffi > makefile
make MODULES=

for clisp-1997-02-11 produces the following output. The blanks  
preceeding dir) are actually \0's in the Makefile. I guess something is  
fishy with makemake? The problem didn't appear with 1996-05-02 (the  
previous release I have had running ok). I'm not using the newreadline,  
just the original readline.
