I applied your patch and make a few additional changes (the new
variables needed to be added to the octave_config_info struct, used in
mkoctfile.in, etc.)

Now mkoctfile uses DL_LD and DL_LDFLAGS and the old
MKOCTFILE_SH_LDFLAGS variable has been replaced by

I think I have the change right, but I don't have a system to use for
testing where there would be a difference between SH_LD and DL_LD, so
you'll need to update your sources and confirm that it works properly.

Good news:
Octave passed all tests
Hello.oct works

* Have to pass -L/opt/local/lib (was specified in LDFLAGS) to mkoctfile for it to find lg2c (FLIBS)

* I forgot to add install names to octave libs (will fix ASAP, set DYLD_LIBRARY_PATH until then)

* Small typo in Makeconf.in

Nevertheless, quite an improvement.
Compiling octave-forge will probably expose the remaining issues.
