# gcc-14 is the default on noble (ubuntu:24.04) but absent from jammy
# (the L4T jetpack r36.4.0 base). LocalVQE specifically needs it; the
# other Go backends compile fine with the default gcc shipped via
# build-essential. So: try gcc-14 from the configured repos, fall back
# gracefully when it's not available so jammy-based builds don't fail
# at the apt step.
