Why is ia64-linux-gnu setting STRICT_ALIGNMENT to true even though it works by
default?

prctl --unaligned=signal will make it generate bus errors.

But that is a different issue and really this should be handled correctly
in that since the target supported by default the unaligned handlers, it
should not set STRICT_ALIGNMENT to 1. Now the target can have an option
to turn it on, witness PPC-elf/PPC-linux which has one as some embedded
hardware/OS's don't support the unalignement trap.
