There is one usage in boehm-gc/os_dep.c, but it is only used if
SUNOS5SIGS is defined, which it is only if one of SUNOS5, DRSNX, HPUX, or
FREEBSD is defined, which are all not using Linux-based glibc ports.

Likewise, gcc/ada/init.c has a struct __siginfo occurence, but only for
__FreeBSD__.

config/rs6000/linux-unwind.h uses ``char siginfo[128]'', and
config/s390/linux-unwind.h also uses a constant.

I tested the following patch for sh-linux-gnu.  This only covers one
configuration, but the change is pretty mechanic anyway and every place
that used to refer to struct siginfo already must have had <signal.h> in
its include path, which is the same file that declares siginfo_t.

OK to commit?  This should probably also go into any active release
branches, to keep them buildable once this glibc change ripples through?

libgcc/
        * config/alpha/linux-unwind.h (alpha_fallback_frame_state): Use
        siginfo_t instead of struct siginfo.
        * config/bfin/linux-unwind.h (bfin_fallback_frame_state): Likewise.
        * config/i386/linux-unwind.h (x86_fallback_frame_state): Likewise.
        * config/ia64/linux-unwind.h (ia64_fallback_frame_state)
        (ia64_handle_unwabi): Likewise.
        * config/mips/linux-unwind.h (mips_fallback_frame_state): Likewise.
        * config/pa/linux-unwind.h (pa32_fallback_frame_state): Likewise.
        * config/sh/linux-unwind.h (shmedia_fallback_frame_state)
        (sh_fallback_frame_state): Likewise.
        * config/tilepro/linux-unwind.h (tile_fallback_frame_state): Likewise.
        * config/xtensa/linux-unwind.h (xtensa_fallback_frame_state): Likewise.
