So far as I know, devel/llvm* builds make no use of WITHOUT_CROSS_COMPILER
definitions ( documented in src.conf ) or what I mention below (also from
src.conf documentation).

As for what is analogous in src.conf's documentation for system
builds: BE_NATIVE in an devel/llvm* for a given context would be
analogous to using a specific mix of:

    WITHOUT_LLVM_TARGET_AARCH64 vs. WITH_LLVM_TARGET_AARCH64
    WITHOUT_LLVM_TARGET_ARM     vs. WITH_LLVM_TARGET_ARM
    WITHOUT_LLVM_TARGET_MIPS    vs. WITH_LLVM_TARGET_MIPS
    WITHOUT_LLVM_TARGET_POWERPC vs. WITH_LLVM_TARGET_POWERPC
    WITHOUT_LLVM_TARGET_RISCV   vs. WITH_LLVM_TARGET_RISCV
    WITHOUT_LLVM_TARGET_X86     vs. WITH_LLVM_TARGET_X86

Some of the mixes would simulate the various devel/llvm* ports
BE_NATIVE's intent for various platforms. (BE_NATIVE does not
work in all contexts, last I tried it anyway.)
