CI failure looks related to #68049.

On Mojave:

This is looking a lot like a mismatched SDK problem too. @fxcoudert, do you know how to fix this? Is it enough to just set

ENV["ac_cv_func_curl_mime_addpart"] = "no" if MacOS.version == :mojave

?

Big Sur error is related to the disappearance of MacOSX11.0.sdk on the latest Big Sur. In progress at #67615.

I'm also wondering if this can be removed:

homebrew-core/Formula/gdal.rb

Lines 142 to 147 in 530732c

	# Work around "error: no member named 'signbit' in the global namespace"
	# Remove once support for macOS 10.12 Sierra is dropped
	if DevelopmentTools.clang_build_version >= 900
	ENV.delete "SDKROOT"
	ENV.delete "HOMEBREW_SDKROOT"
	end

# Remove once support for macOS 10.12 Sierra is dropped 

Comment says yes

[carlocab]

The comment is also ambiguous about whether it's talking about Homebrew support for Sierra (yes), or gdal support for Sierra (dunno). Though I guess Homebrew support is a safe assumption.

[SMillerDev]

Definitely homebrew support, we don't really care what upstream supports (and we're also not going to patch it for versions that homebrew doesn't support)

[carlocab]

Ok, so I've managed to fix the Mojave CI failure, though I don't know if it's the right fix. poke @fxcoudert (again, sorry)

[fxcoudert]

I think, if there is a SDK issue with curl on Mojave, depending on our own curl is probably best.
