Here I'm observing build errors with aarch64-linux-gnu-gcc 12.1.1
20220507 (Red Hat Cross 12.1.1-1):

/tmp/cchqHdeI.s: Assembler messages:
/tmp/cchqHdeI.s:746: Error: unknown architectural extension `simd;'

This is a binutils error not gcc.. What is the binutils version?

2.30 is the lowest that v6.16 supports..
