* gnu/packages/llvm.scm (make-single-arch-llvm): New procedure.
(llvm-native-12, llvm-native): New variables.
---
Using this copy of llvm for packages like mesa will reduce the closure
of those packages. I don't suppose it would work as well for compilers
like rust which use LLVM for compiling and targeting different
architectures.
This drops the size of llvm-12 from 167M to 111M.
