Actually I'd like to understand what we did wrong.  Just to be clear 
because terminology can be different, that's a full 64-bit build for 
64-bit Intel architecture, correct?  That is what we were after. Our 
build command for a gcc release build was:

./b2 --toolset=gcc-8.1 address-model=64 --stagedir=./stage64release 
--build-dir=./build64release --layout=system --without-mpi 
variant=release link=shared threading=multi runtime-link=shared install 
--prefix=./osx64release/indep --exec-prefix=./osx64release/bin 
--libdir=./osx64release/lib --includedir=./osx64release/include

user-config.jam entry is:

# gcc 8
using gcc
 Â Â Â  : 8.1
 Â Â Â  : "/usr/local/bin/g++-8"
 Â Â Â  ;
