Description

ARROW-13199 added -fno-lto flags to the build (see also ARROW-12853). This likely is the cause of the LTO failure on CRAN: https://www.stats.ox.ac.uk/pub/bdr/LTO/arrow.out so we probably need to back it out.

We don't have a CI job that tests with R built with --enable-lto, and AFAICT there is no docker image out there that has one. I will try to get one added to wch/r-debug so that we don't have to build R from source to test this.
