  Version:  Boost 1.66.0                         |   Severity:  Problem

-------------------------------------------------+-------------------------
 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
 }}}
