G'day Peter,
many thanks for your reply. I've tried to leave this option out, but it
produces a similar error:
/usr/pkg/msp430-gcc-4.4.3/bin/msp430-gcc -O2 -s -mmcu=msp430x149 -Wall

The new linker script,
/usr/pkg/msp430-gcc-4.4.3/msp430/lib/ldscripts/msp430x149.x is empty and just
contains a header declaring
that it is the default linker script for normal executables.
