All you have to do is something like:

#-------------------------------------------------------------------------

C_FILES=this.c is.c some.c c.c files.c
O_FILES=$(C_FILES:.c=.o)  # if your make can't do this, do it literally
LIBS=-lpc -lm

program:
        echo $(O_FILES) >link.rsp
        echo $(LIBS)    >>link.rsp
        gcc -o $* $(LDFLAGS) @link.rsp

#--------------------------------------------------------------------------

I have done GOBS of .o files this way.  And, you don't need any fancy
make features, just simple DOS commands.  As I figure it, gcc doesn't care
how many files you put on a line in the response file.  Not so far as I
can tell anyway.  If it does, just break your C_ and O_ macros up.
