Build Update for istokes/ovs

Build: #1006
Status: Passed

Duration: 1 hr, 17 mins, and 15 secs
Commit: 7d0f27a (avx_512_comp_b_2_14)
Author: Harry van Haaren
Message: configure: explicitly disable avx512 if bintuils check fails

This commit explicitly disables avx512f if the binutils assembler
check fails to correctly assemble its input.

Without this fix, there is a possibility that users can see undefined
behaviour when compiling with -march=native on a CPU which supports
avx512 and with a buggy binutils version (v2.30 and 2.31), without a
backported fix, if the compiler's vectorizing optimizations convert
scalar code to avx512 instructions.
