Improved Apple Silicon support (variadic functions) + add tests on apple-silicon-m1 (self hosted runner)

misl6 commented 2 years ago

Now we can run tests also on our apple-silicon-m1 runner.
Removes pre-built CArrayTestlib.dylib and testlib.dylib (These dylib are used during tests, and we're already building them via make test_lib)
make test_lib now builds universal2 libraries, so tests can be done on both Intel and Apple Silicon macs.
Since macOS 10.15 ffi_prep_cif_var is present, and should be used to prepare variadic functions, that otherwise will silently fail on ARM64.
Added a guard via __builtin_available for ffi_prep_cif_var
We are now able to correctly prepare a variadic function also on iOS. (Fixes issue #77 )
