# Release/debug build profiles (explicit opt-in; `make` alone is unchanged).
#
# Mechanism: CFLAGS is passed on the recursive make COMMAND LINE. Automake's
# compile rule ends with `$(AM_CFLAGS) $(CFLAGS)`, so a command-line CFLAGS
# overrides configure's `-g -O2` default while AM_CFLAGS (-std=c23 -Wall
# -Wextra -Wpedantic) is always kept. No configure.ac churn, no default
# build impact. Both targets clean first so a previous profile's objects
# can never be reused as a fresh build.
#
# release: -O2 -DNDEBUG, no -g, then the binary is stripped (needs binutils
#          `strip` on PATH).
# debug:   -g2 only, no -O/-O2, no NDEBUG (default CFLAGS are overridden).
