I am still just learning about the new twists in the MacTel (OS X on
Intel) platform, but I know enough now to ask a question or two. It
seems that the version of gcc that apple ships accepts a new command
line option:

- -arch arch
Compile for the specified target architecture arch. The allowable
values are i386 and ppc. Multiple options work, and direct the
compiler to produce ``fat'' binaries including object code for each
architecture specified with -arch. This option only works if
assembler and libraries are available for each architecture speci-
fied. (APPLE ONLY)

So a developer could produce a ppc, i386, or fat version of a given
artifact. Fat exectuables will run on either architecture. Fat .o's,
etc. will support this. How would this map to bbv2? Would the right
thing be an <arch> featuire with possible values {ppc, i386, fat}?
