Clang: Only build needed target for bootstrap compiler.

Authored by bdrewery on Jun 26 2018, 6:18 PM.



This will disable the new LLVM_TARGET_ALL option which will only
enable the required target.

This only impacts the bootstrap compiler in WORLDTMP, not the target compiler
that will be installed.

Test Plan

Did buildworld with native arch, cross-arch, and testing of the universe-one-clang patch.

Isn't WITH_LLVM_TARGET_ALL the default, and if so, shouldn't WITHOUT_LLVM_TARGET_ALL be documented instead? (I always found these explanatory files a little confusing, though...)

Oh, I just saw the WITHOUT_ file was added in your other review.

Allow overriding MK_LLVM_TARGET_ALL (for one-clang-universe)

Yeah this review is just utilizing the feature for buildworld. The other adds the option as a simpler means to enable/disable unneeded targets for users.
