I did notice that LTCOMPILE wasn't getting set, and I saw the LTCOMPILE= in
the Makefile which was empty, so I knew that was the missing part of that
command, but I couldn't figure out what was causing this.

LTCOMPILE = 
#    if $(LTCOMPILE) -MT $@ -MD -MP -MF "$(DEPDIR)/$*.Tpo" -c -o $@ $<; \
    $(LTCOMPILE) -c -o $@ $<

And I also noticed this during configure:

checking if libtool sucks... yup, it does
checking if dolt supports this host... no, falling back to libtool

Ok, will try that now...
