_unexpected_ is defined in libc.a, which you are not including.
Try using msp430-gcc instead of msp430-ld as the linker. That's usually
safer when linking code compiled in higher-level languages where
language-specific runtime support is needed. (-lgcc is not sufficient in
this case. -lc might be enough.)

Start uncovering the many advantages of virtual appliances
and start using them to simplify application deployment and
accelerate your shift to cloud computing.
