commit 229193666701ddf21002f0156e6d1b86f174d5b6 Author: Bryan Drewery Date: Wed Jun 20 12:42:27 2018 -0700 tinderbox: Only build clang/lld once if needed. Need to handle LLD_BOOTSTRAP separately (for archs like i386). This would be much better off with an off-by-default option like SHARED_TOOLCHAIN that universe force-enabled. Then a normal buildworld would store the toolchain there if enabled and otherwise in WORLDTMP with only the 1 arch selected.
