bind_textdomain_codeset not being available is due to the HAVE_BIND_TEXTDOMAIN_CODESET feature check failing, therefore the extension doesn't create the function.

Unfortunately, this will be super hard to track down with CI only. I can give it a shot on my intel laptop (docker mac) tomorrow.

alt will have default value link to https://dl.static-php.dev/static-php-cli/deps/spc-download-mirror/gmp/gmp-spc-mirror.tar.xz if we haven't defined alt.

Also I don't think we need to change it to crawler for gmp. gmplib.org often down and only updated once every few years.

I'll monitor how often it's down over the next weeks. I still think we should auto-updating sources where ever possible.

I tried it on multiple local OS, and RC3 also failed almost 100%. Only by changing the dependency order can this problem be fundamentally solved.

I've already submitted a PR, but that will likely take a while to take effect.

The headers should already be generated in the release tarballs from Daniel, we can switch to them.

This caused by undefined symbol from macOS CoreFoundation and libiconv. I will try it locally.

I need a real mac, my docker version on the intel laptop is so slow that it takes 30 seconds to do a mouse click.

Edit: giving up, it's been installing php (finished) & composer (ongoing) for the past hour.

@henderkes Ah I forgot the gmplib.org has banned GitHub IPs for a while. Using gmplib.org is fine for users other than GitHub, but we also rely heavily on GitHub Actions, so can't say it's the best choice.
