Automatic cross-platform testing: part 7: 32 bit, again

I have written about this before , but I've had to do it again. I noted previously that Github's actions for things like checking out a repository and for retrieving build artifacts are now 64-bit only. You've been able to work around that by using older versions of the actions but I didn't want to do that so I'm taking a different approach. My new method builds on work I've done previously to pull all my testing for different Unixy platforms together into one workflow. This tests on 64-bit versions of NetBSD, FreeBSD, OpenBSD, IllumOS (that is, the modern version of Open Solaris), and Linux. And as of earlier today it also runs the tests on 32-bit Linux. As in my previous blog entry it's still really 64-bit hardware, with modern x86 ISA extensions, but it's a 32-bit OS image with 32-bit addressing, userland, compiler toolchain and so on. If you absolutely must have a pure 32-bit x86 environment then you'll need to acquire some obsolete e-waste and run it yourself. Something like this
