BTW, JIT CI is broken on macOS and Windows currently, so if those fail (build failure on Windows and 2 failing tests on macOS), it's not your fault.

Technically, this should probably also support CFLAGS_NODIST? I'm not sure.

It's up to you. If you want to add CFLAGS_NODIST, just use the same --with-cflags option to pass them though (the build script doesn't care which is which).

So, this breaks on universal builds, since that sets CONFIGURE_CFLAGS= -arch arm64 -arch x86_64. See the AArch64 macOS failures in CI (it's different from the expected test failures).

I think part of the problem is that we don't want to use an option for the JIT just because it's being used for the interpreter itself. We want very tight control over the code we're generating, especially since the parse step is sort of fragile.

What flags are you needing to pass, exactly? Is it only include paths?

I only need the include flag for my build to pass. But I only caught #134291 because all of my flags were passed through. It's possible there are other subtle differences. I'm totally fine with a CFLAGS_JIT, personally. I feel like people are opposed to new CFLAGS variants, but here it makes a lot of sense.
