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:

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

1 Original patch from: ../4.3.2/110-trampolinewarn.patch
3 -= BEGIN original header =-
4 Original patch from gentoo: gentoo/src/patchsets/gcc/4.3.1/gentoo/00_all_gcc-trampolinewarn.patch
5 This trivial patch causes gcc to emit a warning whenever
6 it generates a trampoline. These are otherwise hard to
7 locate. It is rigged to default ON - to have it default
8 to OFF remove the text 'Init(1)' from the common.opt
9 patch, leaving just 'Common Var(warn_trampolines)'.
