It can be useful to select subtargets, like 'clang' or 'llvm-ar', to build single tools when issues are isolated to them, which can reduce build time. This provides tangible benefits when bisecting, as an issue can be isolated down to a single commit in less time. As part of this implementation, the build target parameter is added as a member to LLVM_Builder and changed to a list to be more flexible and fit in more with how customizing the builder works in the rest of tc_build.
