[IA64-SGI] bte.c: kill expression as lvalue warning

A recent patch caused a warning about not using expressions as lvalues
to crop up in bte.c (or maybe it's just that I'm using gcc-3.4.1 now).
This patch fixes it by creating a temporary to store the register whose
address we want to get and stuff into the per-bte info structure.
