See this comment in elfxx-sparce.c:

			  /* We are turning this relocation into one
			     against a section symbol.  It would be
			     proper to subtract the symbol's value,
			     osec->vma, from the emitted reloc addend,

Since you are writing a new dynamic loader for rtems you have the
opportunity to fix this for rtems.
