Compiling on Arch -_- | WTF |

Try build on ArchLinux using official guide, but no way…
Just “make” successfully compile build, but blender not starting, program to run blender start file is not defined, and offers to choose, and make release not working for this target. (died try) installed all needed dependencies, including LLVM (6.0.1), but when make full, after 5 second - Error, unconfigured / LLVM not found / LLVM config not found
But if install LLVM from Arch rep (8.0.0) and make full - compiling 100% and then errors in end.
If make -j8… from BUILD_NOTES, with and without LLVM 8, also compiling 100% and then errors in end.

What errors?
