fix: Compile Node 22+ for armv6l

[friebi]

Re-enable builds for armv6l.

By switching to Ubuntu 22.04 and gcc-12, I am able to successfully compile Node 22 for armv6l and run it on my Raspberry Pi Zero.
I do not own a Raspberry 1 anymore to test.
I tested with Node 22.14.0.

Fixes #162 and reverts #143.

How can I trigger and test the CI pipeline?

[friebi]

I tried locally all latest major Node JS versions from 16 onwards. 17.9.1 fails with build error, all others succeed, including 16.20.2.

[friebi]

So will this be reviewed and possibly merged?

[rvagg]

sure, why not, please can you guys keep an eye on these builds though, if they don't work for the latest versions of Node then we need to add a limitation for it, or fix it

[friebi]

Thanks!

please can you guys keep an eye on these builds

trying to do so. As you can see in nodejs/node#58458 with Node 24 we might run into trouble again which also seems not so easy to fix. Except @rvagg can update the compilers or give me a guideline/hint on how you created the cross-compilers in https://github.com/rvagg/rpi-newer-crosstools

FYI disabling on v24: #179
