Improve manpage compatability by dropping an abbreviation macro that
compiler upstreams do not want. It was only used in three pages, which
are amended in this commit.
Note, on man.freebsd.org these do not render, because it uses groff:
We have to be really careful about compat, there's 56 years of ecosystem
around manpages that is all generally integrated and working better than
anything else we have. Also our math libraries have a lot of downstreams
which might be using different toolchains.
MFC after: no, these did not MFC
