mesa requires llvm and clang (compiler-rt is needed for clang) , minimal 
may fit that.

I guess it's for cross compilation purposes.

Both extra/llvm and aur llvm-git use llvm default[1] to build all 
supported architecture targets.

The full list of targets is in 
https://github.com/llvm/llvm-project/blob/master/llvm/CMakeLists.txt and 
shows 15 targets.

I'm not sure, but maybe MIPS is the RISC-V architecture ?

*> LLVM_TARGETS_TO_BUILD*:STRING
    Semicolon-separated list of targets to build, or /all/ for building
    all targets. Case-sensitive. Defaults to /all/. Example:
    |-DLLVM_TARGETS_TO_BUILD="X86;PowerPC"|.
