Undefined symbol __availability_version_check with LLVM 17 on macOS Intel (osx-64)

[certik]

We are getting the following linker error with Clang 17 (LLVM 17) on osx intel:

[ 93%] Linking CXX executable test_lfortran
Undefined symbols for architecture x86_64:

See also #94 (comment), the PR that triggered it.

This error does not happen on macOS/arm.

The only workaround that we know about so far is to use Clang 16 / LLVM 16 for macOS/intel.

Thanks @h-vetinari ! If you figure out how to fix it, that would be a huge help.

Can you try again? Should be fixed now...
