AIX -fpic/-fPIC warning

[David Edelsohn]

	The -fpic/-fPIC warning mostly is informational and is occurring
too often, so I am changing it to key off of extra_warnings being
enabled.  check-g++ drops from 42 failures to 19 without all of the
"excess errors".

        * config/rs6000/rs6000.c (rs6000_override_options): Only warn
        about -fpic/-fPIC if extra_warnings set.
