        Fixes for building on 64-bit hosts:
        * config/tc-avr.c (mod_index): New union to allow conversion
        between pointers and integers.
        (md_begin, avr_ldi_expression): Use it.
        * config/tc-i370.c (md_assemble): Add cast for argument to print
        statement.
        * config/tc-tic54x.c (subsym_substitute): Likewise.
        * config/tc-mn10200.c (md_assemble): Use a union to convert the
        opindex field of fr_cgen structure into a pointer so that it can
        be stored in a frag.
        * config/tc-mn10300.c (md_assemble): Likewise.
        * config/tc-frv.c (frv_debug_tomcat): Use %p to print pointer
        types.
        * config/tc-v850.c: Replace uses of (int) casts with correct
        types.
