I can't see anything particularly weird about chsm offhand.  My 
first worry is that the warnings are catching up to you and tripping
some sort of bug in m68k-elf ld.  

Does this compile cleanly natively?  The gcc for RTEMS is just a
normal gcc targetting m68k.

Another thing to consider is that you probably REALLY
wanting to link with m68k-rtems-g++.  Some BSPs have a 
"make-cxx-exe" rule.  Your makefile should use that
not the make-exe rule.  You may have to add one to the efi332 
BSP's efi332.cfg custom file.
