On further thought, since gcc of that era thought it knew all about the
different chips the MSP:200 is probably being extracted from a value
written into the object file by the assembler based on information encoded
by gcc.
Based on the timeframe, I believe support for msp430f2012 was added after
development of mspgcc 3.x mostly stopped, so it may be that it never
worked, or that you've somehow got a combination of gcc and binutils where
that chip isn't consistently handled between the toolchain elements.
