Comment (by kencu):

 The little patch to disable the error when redefining asm labels (to give
 clang the behaviour it had before this test was added in clang-3.8) does
 in fact work, and it allows software that failed with this error to now
 build. That looks suitably low risk, I believe, that we could consider
 that as a fix until/unless we come up with some more elegant method to use
 by tweaking <sys/cdefs.h> in the legacysupport headers, perhaps.
