GCC provides some of std* headers including stddef.h
and it syncs with glibc definitions via __needed* defines
to find which datatypes are expected to be defined on top
of glibc. we need same for musl.

- NEON is not available
-
- PR target/71056
- * config/arm/arm-builtins.c (arm_builtin_vectorized_function): Return
- NULL_TREE early if NEON is not available. Remove now redundant check
- in ARM_CHECK_BUILTIN_MODE.
-
- * gcc.target/arm/pr71056.c: New test.
