# Portable across GNU make (Linux) and BSD make (FreeBSD).
#
# We do NOT read the make flavor's predefined CFLAGS: BSD make's sys.mk sets it
# to "-O2 -pipe", which would fight our OPT setting. Optimization lives in OPT,
# required language/warning flags in STD/WARN, and EXTRA is yours to append.
#
# OPT defaults to an aggressive, build-on-target profile. -march=native tunes
# for THIS machine's CPU, so only build where you run (which is how this repo
# is used). If you cross-build, override it, e.g.  make OPT="-O2".
