math/R maintenance

[Fernando Herrero Carrón]

Hi everyone,

Some time ago I submitted a patch [1] to add some optimization related
options to math/R (choose with BLAS library to link against and add LTO,
basically). The PR has not received much attention since then, and the
maintainer hasn't replied to my emails either.

The Makefile of the port seems somewhat outdated as well and could use some
improvements. If the port needs a new maintainer I would volunteer, even
though I have no previous experience. At the very least I could certainly
help putting it into shape and testing it.

Best wishes,
Fernando
