>Description:

The following targets have target options but no documentation of them
in invoke.texi:

1750a
dsp16xx
elxsi
fr30
i370
i860
pj

(stormy16's undocumentedness is already the subject of a separate PR.
we32k has no target options at all.)

>How-To-Repeat:

Look for documentation of the target options of these targets.

>Fix:

Document the target options of these targets.
