When llvm10 is built with LTO (i.e. lto is enabled in OPTIONS in makepkg.conf), clang10 fails to build against it, failing with a ton of "undefined reference" errors when linking clang-tblgen.

LTO is enabled by default in devtools, used by aurutils when building AUR packages in a chroot. That means, aur sync -c clang10 will fail, unless llvm10 is built without LTO.

Any ideas how it can be fixed (aside from filtering out -flto from CFLAGS in PKGBUILD)?

Sample of errors:

Thank you, added.

I encountered the following error when building this package with extra-x86_64-build:

-- Installing: /build/llvm10/pkg/llvm10/opt/llvm10/lib/cmake/llvm/./GenerateVersionFromVCS.cmake
-- Installing: /build/llvm10/pkg/llvm10/opt/llvm10/lib/cmake/llvm/./LLVMExternalProjectUtils.cmake
~/llvm10/src/llvm-10.0.1.src/utils/lit ~/llvm10/src/llvm-10.0.1.src/build
Traceback (most recent call last):
  File "/build/llvm10/src/llvm-10.0.1.src/utils/lit/setup.py", line 4, in <module>
    from setuptools import setup, find_packages
ModuleNotFoundError: No module named 'setuptools'
==> ERROR: A failure occurred in package_llvm10().
    Aborting...

I then added python-setuptools as makedepends and the package is built successfully with extra-x86_64-build. I think python-setuptools should be added as makedepends.
