[patch committed SH] Fix help text for -mfdpic

[Kaz Kojima]

I've committed the attached obvious patch to fix

FAIL: compiler driver --help=target option(s): "^ +-.*[^:.]$" absent from 
output: "  -mfdpic                     Generate ELF FDPIC code"


popping up after SH fdpic patch applied.

Regards,
        kaz
