#     -mlinker-version
#
#         Ensures that modern linker features are enabled. See here for more
#         details: https://github.com/bitcoin/bitcoin/pull/19407.

#     -B$(build_prefix)/bin
#
#         Explicitly point to our binaries (e.g. cctools) so that they are
#         ensured to be found and preferred over other possibilities.
#
#     -isysroot$(OSX_SDK) -nostdlibinc
#
#         Disable default include paths built into the compiler as well as
#         those normally included for libc and libc++. The only path that
#         remains implicitly is the clang resource dir.
#
#     -iwithsysroot / -iframeworkwithsysroot
#
#         Adds the desired paths from the SDK
