empty line in compilation rules

[Lars J. Aas]

When I run CVS Automake, the .c.o and .c.lo rules become like this:

| .c.o:
| 
| @AMDEP@ source='$<' object='$@' libtool=no @AMDEPBACKSLASH@
| @AMDEP@ depfile='$(DEPDIR)/$*.Po' tmpdepfile='$(DEPDIR)/$*.TPo' 
@AMDEPBACKSLASH@
| @AMDEP@ $(CCDEPMODE) $(depcomp) @AMDEPBACKSLASH@
|         $(COMPILE) -c -o $@ `test -f $< || echo '$(srcdir)/'`$<
|
| .c.lo:
| 
| @AMDEP@ source='$<' object='$@' libtool=yes @AMDEPBACKSLASH@
| @AMDEP@ depfile='$(DEPDIR)/$*.Plo' tmpdepfile='$(DEPDIR)/$*.TPlo' 
@AMDEPBACKSLASH@
| @AMDEP@ $(CCDEPMODE) $(depcomp) @AMDEPBACKSLASH@
|         $(LTCOMPILE) -c -o $@ `test -f $< || echo '$(srcdir)/'`$<

GNU make seems to handle the empty first line, but IRIX MIPSPro make
doesn't.
