I want to build R (https://cran.r-project.org/) on (B)LFS 8.0 and one of its dependencies is a Fortran compiler. According to the BLFS book, adding Fortran to GCC requires a full recompilation, and this is done by bootstrapping, which "is needed for robustness and is highly recommended when upgrading the compilers [sic] version." I won't be upgrading, just adding Fortran, so will it save significant time to configure with --disable-bootstrap, or is that too risky? But the biggest time sink is the test suite: my LFS system is running on a not very fast single core CPU and the first full build of GCC with the tests took more than 10 hours (9 for the test suite). Since I will be recompiling the same version of GCC on the same hardware, but just adding Fortran, is it reasonable to skip the test suite this time, or is that too big a risk?
