If you were really curious, you could try to install different versions of GCC, and recompile something (like zip/bzip/gzip) and see if that made a difference.

Curious, yes. Free time to spend/spare on such a venture, no. :D

I found changelogs, if you scroll down, there is an ARM section. Lots and lots of changes (most of which I dont understand):
GCC 6
GCC 7
GCC 8
GCC 9

Thanks for the info and advice Re: gcc. If you don't understand most of the above then at least we're in a similar position. :D
The only thing I was already aware of in gcc-9.1 is the added support for Cortex-A55 and A76 CPUs. Everything else [ARM related] is pretty much news to me. Reading these changes makes me appreciate just how much everything would be affected, as you wrote.
Really good educational stuff. Cheers!
