It was not, I think. The commit that added this functionality is:

        r50172 | vladimir_prus | 2008-12-07 11:25:41 +0300 (Sun, 07 Dec 2008) | 4 lines

        Support for 32+64 fat binaries on Darwin.

        Fixes #1679.

So I suspect it did not even make it into 1.38. OTOH, you can grab Boost.Build
from trunk, or from nightly builds at and replace
the copy in your 1.36 tree.

Note that the right way to request 32+64 binaries is via:

        architecture=x86 address-model=32_64

you can also use:

        architecture=ppc address-model=32_64


        architecture=combined address-model=32_64
