Subject: [PATCH 196/325] tools/build/options/makeman: Add silly hack to deal
 with options that have no description (XXX)

If the option doesn't have a description file it's likely that
the opposite option does have one. If it does, use its opossit
and hope for the best.

XXX: Does not confirm that the meaning of the description has
actually been reverted by the sed calls.
