Makefile: Improve Apple detection

[sevan]

__APPLE__ is always defined & set to 1 on Darwin.
__apple_build_version__ not available on older releases.
This change allows Capstone to build on OS X 10.4.

Note though that the Makefile build method is effectively deprecated and will be dropped in the future.

[sevan]

Understood. It would be a shame since cmake has such a high cost.
I can build capstone 5.0.1 with GCC 4.0 on OS X 10.4, but cmake needs a C++11 compiler from cmake 3.10 onwards & may need an even more recent C++ compiler on current releases, so effectively that will become capstone's minimum requirement.

Just opened an issue where you can describe your use case. So we have tracked it somewhere (#2264).
@kabeor, please trigger the CI.

[sevan]

Thanks, I'll follow up there later on tonight when I have some time. Just popped in to ask if something is wrong on the CI side?

[sevan]

@Rot127 Is there something wrong with the CI here or have I missed where it's going wrong?

[Rot127]

Yeah, something is broken currently.

[sevan]

No worries. Thanks for the sanity check. :)

[kabeor]

6a55ef3 should fix the CI, please push a commit to trigger it.

[sevan]

Done.

[kabeor]

Cool, thanks!
