Comment (by kencu):

 using gcc to build things usually forces the ancient Apple gas assembler
 which is very outdated.

 any current clang should work

 https://github.com/oneapi-
 src/oneTBB/blob/7340a880885cfec2bf05d981e83e44612d1efb6e/include/oneapi/tbb/detail/_config.h#L338

 or you can use the macports cctools mod that uses a newer clang as
 assembler,

 or you can alter the test to disable the tpause functions in tbb instead:
