I wasn't pointing at anything related to making libunwind of general
use. The issue is that you're using $target to detect when to include
libunwind-ia64.h. That's broken for the --enable-targets=all,
or --target=x86_64-foo --enable-target=ia64-xxx cases, when --target is _not_
ia64-*. That is, it looks to me that the fix should be to make sure we include
libunwind-ia64.h in ia64 relative code, no matter the $target. Or maybe I missed
