The use of vector types such as __Float32x4_t in the aarch64 math-
vector.h header breaks quite a few programs that are essentially parsing
C code but using GCC as their preprocessor. GCC expands to the paths
using its own intrinsic types, which aren't implemented by the consuming
programs.

I'm not sure if this qualifies as a bug in glibc, as it seems reasonable
to rely on those types, but we've seen this happen in quite a few
instances in Ubuntu:

  Marking as critical as this blocks the glibc transition.
