Ack. Per upstream's defaults enabling this feature requires -msse4.2 on
amd64 and -march=armv8-a+simd on arm64, cf.
<https://github.com/rsyslog/liblognorm/blob/main/configure.ac#L185> ff.
and this seems to go beyond their current respective arch baselines, cf.
<https://wiki.debian.org/ArchitectureSpecificsMemo#Architecture_baselines>,
so perhaps the scalar fallback (functional but without SIMD
acceleration) will need to be utilized instead, cf.
<https://github.com/rsyslog/liblognorm/blob/main/doc/turbo.rst#building-with-turbovm>.

Also, there are known differences from the standard engine, cf.
<https://github.com/rsyslog/liblognorm/blob/main/doc/turbo.rst#known-differences-from-the-standard-engine>,
so I guess I will give this some testing in Experimental first.

Cheers,
Flo
