Jang, Bongseo dcd88fbd99 debug/gdb: fix from upstream with newer glibc(siginfo vs siginfo_t, Gentoo gdb-7.4.1 patch) 
This is for when you failed to build gdb-native with the error:

	gdb-7.4.1/gdb/linux-nat.h:79:18: error: field 'siginfo' has incomplete type"

This is from mirror://gentoo/distfiles/gdb-7.4.1-patches-2.tar.xz

fix from upstream for building with newer kernel headers

Subject: [PATCH] struct siginfo vs. siginfo_t
gdb/
* amd64-linux-nat.c (amd64_linux_siginfo_fixup): Use siginfo_t instead
of struct siginfo.
* arm-linux-nat.c (arm_linux_stopped_data_address): Likewise.
* ia64-linux-nat.c (ia64_linux_stopped_data_address): Likewise.
* linux-nat.c (linux_nat_siginfo_fixup, siginfo_fixup)
(linux_xfer_siginfo, linux_nat_set_siginfo_fixup)
(linux_nat_get_siginfo): Likewise.
* linux-nat.h (struct lwp_info, linux_nat_set_siginfo_fixup)
(linux_nat_get_siginfo): Likewise.
* linux-tdep.c (linux_get_siginfo_type): Likewise.
* ppc-linux-nat.c (ppc_linux_stopped_data_address): Likewise.
* procfs.c (gdb_siginfo_t): Likewise.
gdbserver/
* linux-arm-low.c (arm_stopped_by_watchpoint): Use siginfo_t instead of
struct siginfo.
* linux-low.c (siginfo_fixup, linux_xfer_siginfo): Likewise.
* linux-x86-low.c (x86_siginfo_fixup): Likewise.
* linux-low.h: Include <signal.h>.
(struct siginfo): Remove forward declaration.
(struct linux_target_ops) <siginfo_fixup>: Use siginfo_t instead of
struct siginfo.
