Thomas answer still applies: if you can use QEMU v8.0.0 to emulate
macOS 9 on your Huawei Matepad T8 with 32-bit Android, why worry
about trying to use future QEMU versions?
Because Termux (only one currently supported distro for bare Android, as far as I know, everything else either unsupported or run under it, with some space penalty due to not using Android's libraries) will update qemu As Fast As Possible, being rolling release.
Again, I as maintainer/developer (due to our real developer being dead from road incident) of cinelerra-gg I only can recommend to try your favourite projects in somewhat constrained environment, I tweaked our build system quite heavily simply because I was forced by device's constrains.
Also, for CI thing may be lessen compiler optimization levels at least for some runs? And/or tweak ccache compression ....
