gcc-7 (in stage 4) won't have the necessary support for aarch64
libmvec so it's hard to justify the urgency, i.e. upstreaming
most likely won't happen in this glibc release cycle.
(some discussions can start earlier though.)

i'm not sure what target specific implementation means in this
context: i expected at most two sets of math functions for the
two aarch64 simd variants (advsimd and sve).
