--help should list the available options.
As you know, the NetBSD assembler is the GNU assembler. The GNU
assembler documentation is available here:
Specifically, m68k options are listed here:

I haven't tried it, but it looks like %SECMBAR should be available if
you use the -mcfv4e option. Apparectly %SECMBAR is not available on
all variants of the m5200. Or gas is wrong, which is quite possible.
I don't see %MBAR2 listed anywhere in gas, although %MBAR, %MBAR0, and
%MBAR1 should be available using -mcfv4e.
