We had a bug in older assembler, which we still support, where it could not handle constructs like,

        .long   (Ltmp5-Ltmp4)-4

This required use of .set

However in this case we emitting reference to label directly without doing any arithmetic so it should be OK. If all testings looks OK, please go ahead and commit. If someone complains from our side, I'll let you know!
