sci-libs/linbox: use mathjax for inline formulas in API docs
This adds a runtime dependency, but avoids the (so far missing) build-time latex dependency. At the expense of a small rendering penalty, the mathjax formulas look much nicer. Closes: https://bugs.gentoo.org/913192 Signed-off-by: Michael Orlitzky <mjo@gentoo.org>
