27ee3bcd79 OSX/ARM64: Disable external unwinding for now. 
This reduces functionality, e.g. no handling of on-trace errors.
Someone with very deep knowledge about macOS and MACH-O/DWARF stack
unwinding internals is needed to fix this. See issue #698.

81a797373f Fix minilua vararg stack handling. 
Note: this is not exploitable! minilua is only used during the LuaJIT
build process. It only runs controlled and static Lua code (DynASM),
which is entirely contained within this repo. LuaJIT itself has
completely different stack handling code and is not affected either.

This change is solely for the benefit of others, who might possibly use
minilua for purposes other than running DynASM.
