custom linker script, using non-standard switches etc. Anything out of
the usual.
I think the next thing to do is figure out what linker script is being
invoked (I'm not sure how to do that).
The linker script tells the linker where things are supposed to live. I'd
see if I could find the linker script for the 1611 in the new toolchain and
the mspgcc4 toolchain and see if they are different.
If that doesn't yield any insight, kicking this to Peter would make sense.
See what you can figure out looking at linker scripts and then submit a
tracker bug.
