sys-devel/llvm: Fix implicit dependency on app-arch/libxar

Support conditionally using app-arch/libxar in LLVM 6+, and explicitly
force it off in LLVM 5. This library is used only to dump LLVM bitcode
in Mach-O files and it's very rare, so we can safely presume that nobody
really used it and it's not worth rebuild due to revbumping LLVM 5.
