1. kldload filemon # and perhaps auto-load it with /boot/loader.conf or /etc/rc.conf
2. echo WITH_META_MODE=yes >> /etc/src-env.conf
3. for /etc/src.conf:

WITHOUT_LLVM_TARGET_ALL=
WITH_LLVM_TARGET_X86=
WITHOUT_CLANG_FULL=

4. If its resources are really constrained, also add this to /etc/src.conf:

WITHOUT_KERNEL_SYMBOLS=
WITHOUT_DEBUG_FILES=
WITHOUT_TESTS=
