Pass SDK root to the linker as -isysroot, not -Wl,-syslibroot

The former option to clang will result in more options to the linker,
such as the newly introduced -platform_version, which writes the
SDK version to the resulting binary. By using the syslibroot flag
directly we were missing the platform version, and binaries were
left without an SDK version set, resulting in failed validation
of the binary. Going with the clang driver gives us the right
behavior for free.
