Those variables don't appear in the .i files; they only appear in the
code generated by SWIG. However, they do end up in all of the *_wrap.c
files.

As you're getting an error at link time, rather than compile time, I'd
suspect a library mismatch. I note that the only -L switches are those
which refer to dist.<arch>.

I also note that there is no utils_LIBS variable in
swig/python/Makefile (as it doesn't depend upon any GRASS libraries). 
As everything except utils and date[1] has $(GISLIB) as a dependency
(directly or indirectly), I suspect that it may be fixed by defining
utils_LIBS as either some subset of $(XDRLIB) $(SOCKLIB) $(INTLLIB) or
as $(GISLIB).

[1] However, if the date module compiles, that undermines this theory.

Beyond that, I can only suggest comparing the successful linking
commands for the other modules against the failed command for the
utils module.
