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 LLVMBuilder 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/.
