# Explicit distcc routing. fermi's makepkg.conf has
# BUILDENV=(distcc ...) which auto-prepends /usr/lib/distcc/bin to
# $PATH, but mach's configure picks up CC/CXX from the env directly
# and the distcc wrappers won't fire unless we set them. Mirrors the
# ffmpeg-v4l2-request-fourier pattern.
#
# Note: only the C/C++ portion of the build distributes; rustc and
# the host-only build steps stay local. Empirically that's still a
# 30-40% wall-clock win on a 4-worker pool. DISTCC_HOSTS comes from
# makepkg.conf ('+zeroconf' by default — Avahi-discovers tesla,
# dcc1, dcc2, ampere).
