Minor cleanup in rs6000.c

Minor cleanup in rs6000.c

[Stan Shebs]

There were a couple bits of rs6000 detritus that appeared to be left 
over from
one of the big merges in 2000.  Checked in as obvious, bootstrapped on
powerpc-apple-darwin just to be paranoid.

        * config/rs6000/rs6000.c (rs6000_emit_prologue): Remove unused
        local var dwarfp.
        (output_compiler_stub): Remove unused locals.
        (output_call): Always initialize line number.
