Description Richard Yao (RETIRED) gentoo-dev 2018-08-03 14:43:16 UTC 
llvm-config being a binary breaks cross compilation of dependent packages because the host architecture's binary gives us information needed to build for the host while the target architecture's binary cannot be executed by the build system.

This is an upstream bug, but we really could use a patch either switching us to pkgconfig or making llvm-config a script.

Given the current state of affairs, upstream developers seem to be more in favor of replacing llvm-config use with CMake modules.

Is this fixed in trunk?

No, sadly. Added some relevant See Alsos. https://github.com/llvm/llvm-project/issues/58984 is the latest.
