This is a cross build on sparc64 for m68k.
Sparc64 and m68k don't have the same alignment rules.
base is a malloc'd area that is aligned for all purposes.
ra->r_offset is not necessariliy a multiple of 4.
base + htobe32(ra->r_offset) is therefore not longword aligned.
Writing to that address via a u_int32_t* on sparc64 causes a bus error.
