I take it from the patch that linux-tdep.c:linux_get_siginfo_type wouldn't
work for sparc64? Why is that? What's different?
These are the differences of glibc's bits/siginfo.h in sparc with
respect to bits/siginfo.h in x86:
- The _sigfault struct has an additional field `int si_trapno'.
- The `si_band' field in the `_sigpoll' struct is of type `int' instead
of `long int'.
It would be nice to avoid all that code repetition, but since glibc
maintains per-target bits/signinfo.h files more differences could be
introduced in the future...
