Afaik LLVM/Clang doesn't need bootstrapping from source for cross-compiling, but you can choose to include/exclude target support at build time. GCC and binutils can only have one target. Was the LLVM/Clang build done for building a cross compiler to build Minix or was it to build a compiler that runs on Minix? The latter would be unavoidable, but for the former just having LLVM pre-installed on the build machine should do.
