Do the target object file name hacking in "make depend" earlier, before the
line breaks are recomputed, instead of after.  This will result in lots of
whitespace changes in dependencies in directories that build library object
files, but the final output is nicer (fewer long lines), and running "make
depend" uses one fewer invocation of sed (balancing out the extra one I added
in another checkin earlier today).

* config/post.in (.depend): Don't do target name munging here.
(.depfix2.sed): Pass extra value $(STLIBOBJS).
* util/depfix.sed: Don't change foo.o to $(OUTPRE)foo.$(OBJEXT) here.
* util/depgen.sed: Add new argument for STLIBOBJS.  Do the OUTPRE/OBJEXT
substitution here, and if STLIBOBJS is non-empty, add foo.so and foo.po while
we're at it.
