Yeah, the tools are getting stricter all the time - but we don't want
to merge code we can't build with the toolchains included in current
long-term supported Linux distributions.
What does your setup look like today - are you on Windows or Linux?
If Linux, can you use WSL?
Cross compilation tools for both ARM and AARCH64 (and the very latest
ones Ia32/X64) are available in several current Linux distributions
(and hence in WSL).
Best Regards,
Leif
