This is a non-starter because the relevant standards already require
the tv_nsec member to have type long. x32 just needs to be fixed to
match the requirement. This is really easy to do; just change the
definition to have the appropriate padding. Don't make a huge mess for
the sake of a barely-used target that just had a messy but fixable
bug.
