Building with Homebrew llvm/clang fails with error: 'TARGET_OS_IPHONE' is not defined #5622
Description
What did you do?
On latest Homebrew on macOS 11.4 (x86_64) installed llvm package, and tried to build Pillow with
clang/clang++ it provides.
What did you expect to happen?
that it just works (many Python packages build just fine in such a setup)
What actually happened?
error: 'TARGET_OS_IPHONE' is not defined quite early in the build, compiling _imaging.c
