13454,universal 32/64 bits build broken on macOS (worked until 1.65.1),Frédéric Devernay <frederic.devernay@…>,,"Since boost 1.66.0, when configured with `architecture=x86 address-model=32_64`, the build system forgets to add `-arch i386 -arch x86_54` to the compilation flags (although they are still present in the link flags).
The resulting libraries thus contain only the build arch.

Boost 1.65.1 correctly builds universal libraries.

to reproduce:
{{{
./bootstrap.sh --without-libraries=mpi --without-libraries=context --without-libraries=coroutine
./b2 -d2 --debug-configuration architecture=x86 address-model=32_64
}}}
