Okay.  Here's what I can do:

- define new types ASM_GAS, ans ASM_MASM which
  inherit from ASM.  (It's also possible to
  switch on a feature, but I think different types
  is a more correct abstraction.)
- define two new tools gas and masm which can
  be initialized like this and which override
  the default assembler for the corresponding types

  using gas : [command] ;
  using masm : [command] ;

- in your Jamfile, specify the types of the asm files with
  [ cast make_i386_ms_pe_masm asm-masm : asm/make_i386_ms_pe_masm.asm ]

At this point:
- If the assembler provided by the toolset can handle
  the format, then everything should work.  (As is
  the case now.)
- If not, then it can be fixed by adding a line to
  user-config.jam or project-config.jam.

It would also be possible for you to try to auto-configure
the assembler, but I'm not sure that's a good idea, since
it overrides the toolset which is supposed to be the
primary means of compiling.
