Hi,

sparc64 is picky about the locations it accepts write to, so three places
in elf2bb main give bus errors. The attached patch takes care of that.

There is another consideration regarding the code that strikes me as
un-pretty, even though it's not effecting anything:
I think the '*((u_int32_t *)(base + htobe32(ra->r_offset))) =' should
read '((u_int32_t *)(base + betoh32(ra->r_offset))) =' seeing that we
likely transfer a amiga-elf (and thus itself already big-endian) value
into a host pointer increment. Of course the point is entirely cosmetic 
as the two macros do exactly the same. :-)
