LLVM/clang (x86_64) builds (on sabotage) with the small patch (in the 
attached file), but there are 15 test failing (mostly segfaults at 
include/llvm/Type.h:133, see attached log):

Failing Tests (15):
     LLVM :: Instrumentation/AddressSanitizer/instrument_global.ll
     LLVM :: 
Instrumentation/AddressSanitizer/instrument_initializer_metadata.ll
     LLVM :: Instrumentation/ThreadSanitizer/atomic.ll
     LLVM :: Instrumentation/ThreadSanitizer/read_before_write.ll
     LLVM :: Instrumentation/ThreadSanitizer/read_from_global.ll
     LLVM :: Instrumentation/ThreadSanitizer/tsan_basic.ll

In "[musl] Summary of 1.0 marketing plan/scheme/nefarious plot from 
IRC." thread there is pt. "- push "musl support" patches to other 
projects upstream all at once" — it's better to send patches to musl@ 
mail-list and leave it here or what?
