Malformed mach-o on macOS 12.5 (M1)

[shoe42]

Building using the default -pagezero_size and -image_base arguments results in an executable that cannot be executed (M1, macOS 12.5, LLVM 13, using LuaJIT commit https://github.com/LuaJIT/LuaJIT/commit/3065c910ad6027031aabe2dfd3c26a3d0f014b4f):

$ lldb ./bin/terra               
(lldb) target create "./bin/terra"
Current executable set to '.../terra/build/bin/terra' (arm64).
(lldb) r
error: Malformed Mach-o file

As per https://github.com/LuaJIT/LuaJIT/issues/649#issuecomment-751341864, are the flags still necessary with LuaJIT 2.1? Perhaps this isn't being caught in the tests due to the binary not actually being executed?

We test on x86 Mac all the time (both in CI and locally). So I guess this is an ARM64 issue.

The lines you linked to are for the "plain" tests, but we always run in CMake (except on Windows).

If you'd like to send a PR to delete these lines, I'd be happy to take it if it passes:

If it would help to pin https://github.com/LuaJIT/LuaJIT/commit/3065c910ad6027031aabe2dfd3c26a3d0f014b4f, I'd be happy to take a PR for that too.

Looks like the LuaJIT version doesn't affect this specific issue. PR: https://github.com/terralang/terra/pull/589.

One other thing I forgot to mention is that "stock" clang (from clitools) had some issues finding header files (unrelated to this) - I'll open a separate issue for that.
