* solib.c (symbol_add_stub): Remember the index and the name of
        the section with the lowest address. Use this data (instead of
        data from .text) to pass info into symbol_file_add.

        * elfread.c (record_minimal_symbol_and_info): Use the section
        where the symbol lives to get the index, instead of guessing.

Make Sparc a Multi-Arch target. Discard PARAMS macro (require ANSI).
* sparc-tdep.c: include arch-utils.h.
