Considering this problem further, I don't see a way to avoid the CLANG compiler
error with a function implementation. We would need a macro implementation
similar to CLANGS arm_neon.h. In addition, it may be necessary to provide
separate implementations for CLANG and non-CLANG compilers since

After looking at this a bit closer today, I realize that my assertion that
CLANG14 does support vcopyq_laneq_u32() for 32bit ARM was incorrect. It does
not. The reason that disabling the implementation in rte_vect.h works for our
clang builds is that we do not build the l3fwd app nor the ixgbe
+Arm folks.

Hey folks,
We are building DPDK with clang14 for a 32bit armv8-a based CPU and ran into a
