Hi Jia-Shiun! I submitted the gnu/usr.bin/groff portion of your patch in r275866 . I’m going to look at stripping down bootstrap-tools, et al a bit more in the next couple days and I’ll be using your patch in part with some parallel efforts I’ve done on a branch on my github fork as well: https://github.com/yaneurabeya/freebsd/tree/faster-build . Thank you!
