"R Installation and Administration"
<https://cran.r-project.org/doc/manuals/r-release/R-admin.html>
contains a detailed set of instructions on how to compile R, including
section 2.7.4 about the use of LTO. Start with Appendix A, which lists
the packages you would need to install on your Ubuntu (basically,
build-essential, gfortran and the libraries mentioned there). Good luck!
