Two patchoids for Linux-Alpha.
First patch: some architectures define fewer signals. See signal(7).

Second patch: I get obnoxious `unaligned trap' messages in my syslog.
The following fixes it. I think the `temp' variable should be an __u32
instead of an int, but I don't want to start a code audit of word length
assumptions. This fixes the unaligned access, nothing more.
