Building I don't think the options are related to the build error. > LLVM takes a long time on my 7+ year old, memory constrained (8G) > system. Anything that reduces that time would be nice. By the way, before these options get out of hand... I am adding a new WITHOUT_LLVM_TARGET_ALL option to more easily disable unneeded targets which will be simpler for user maintenance. And I am going to make buildworld automatically disable unneeded targets for the bootstrap compiler. For the installed compiler it will still default to all targets. If targets are disabled then SYSTEM_COMPILER logic will fail when cross-building and you will need to build another bootstrap compiler.
