Well, the package works because of this section in Makefile.common:

.if !empty(PKGSRC_COMPILER:Mclang) || ${OPSYS} == "DragonFly" \
    || ${OPSYS} == "NetBSD"
# GCC 16.1.0's stage2/stage3 bootstrap comparison currently fails on
# NetBSD/x86_64, so disable it. Revisit on updates.
# https://gcc.gnu.org/pipermail/gcc-help/2026-August/145120.html
CONFIGURE_ARGS+=       --disable-bootstrap
.endif

Did you comment out that CONFIGURE_ARGS line when testing?
