21  #     -mlinker-version
22  #
23  #         Ensures that modern linker features are enabled. See here for more
24  #         details: https://github.com/bitcoin/bitcoin/pull/19407.
25  #
26  #     -isysroot$(OSX_SDK) -nostdlibinc
27  #
28  #         Disable default include paths built into the compiler as well as
29  #         those normally included for libc and libc++. The only path that
30  #         remains implicitly is the clang resource dir.
31  #
32  #     -iwithsysroot / -iframeworkwithsysroot
33  #
34  #         Adds the desired paths from the SDK
35  #
36  #     -platform_version
37  #
38  #         Indicate to the linker the platform, the oldest supported version,
39  #         and the SDK used.
40  #
41  #     -no_adhoc_codesign
42  #
43  #         Disable adhoc codesigning (for now) when using LLVM tooling, to avoid
44  #         non-determinism issues with the Identifier field.
45  #
46  #     -Xclang -fno-cxx-modules
47  #
48  #         Disable C++ modules. We don't use these, and modules cause definition issues
49  #         in the SDK, where __has_feature(modules) is used to define USE_CLANG_TYPES,
50  #         which is in turn used as an include guard.
