Just for the next poor soul who may attempt something like this; I wanted to let everyone know that the problem stems from the blackfin compiler ABI which prepends an underscore to all symbols. Then for whatever reason the GNU automake environment (specifically configure.in and/or Makefile.in) sets LIBTOOL_EXPORT_OPTIONS in such a way as to NOT allow the exporting of symbols preceeded with an underscore.
 simply changing every instance of:
  LIBTOOL_EXPORT_OPTIONS='-export-symbols-regex "^g.*"'
 helped me get past that problem. I make no claim that this is the best way or even a correct way to address the problem, but right now it is the only way I have found.

You're probably better off asking those people who had the same problem.
