A basic build with xlc 16.1 still succeeds building world-bin. Including
obviously cyrillic_and_mic.so

../configure PERL=perl64 --cache ../config-ac-xlc.cache --with-perl CC=/opt/IBM/xlc/16.1.0/bin/xlc_r CFLAGS="-qmaxmem=33554432 -qsuppress=1500-010:1506-995 -qsuppress=1506-010:1506-416:1506-450:1506-480:1506-481:1506-492:1506-944:1506-1264 -qinfo=all:nocnd:noeff:noext:nogot:noini:noord:nopar:noppc:norea:nouni:nouse -qinfo=nounset"

with OBJECT_MODE=64 previously set.

I'll try a build closer to Noah's configure options. Most likely candidate
seems --enable-debug.
