Right, these two programs are built differently. Yet, just like you,
I don't see any difference in the headers:

% readelf -e $(which pandoc) | grep -A1 OPENBSD_NOBTCF
  OPENBSD_NOBTCF 0x0000000000000000 0x0000000000000000 0x0000000000000000
                 0x0000000000000000 0x0000000000000000    E    0
% readelf -e $(which cabal) | grep -A1 OPENBSD_NOBTCF
  OPENBSD_NOBTCF 0x0000000000000000 0x0000000000000000 0x0000000000000000
                 0x0000000000000000 0x0000000000000000    E    0

Yeah, if you can figure out when this started happening, it would be
helpful.

Thanks
