Sanitize RISC-V GAS help text, documentation

It looks like I missed the GAS help text when going through all the
documentation last time, so it printed some of the old-format (never
upstream) arguments.  I fixed this, and when I went to check doc/ I
noticed it was missing the '-fpic'/'-fno-pic' options.
