gcc: backport an upstream patch to make it work with newer glibc.
Newer glibc removes 'struct' tag from ucontext_t. Because of this, gcc failed to bootstrap with newer glibc. This patch from upstream fixes that. BUG=chromium:834385 TEST=sudo emerge sys-devel/gcc passes with newer glibc installed. commit 14c2f22a1877f6b60a2f7c2f83ffb032759456a6 Author: jsm28 <jsm28@138bc75d-0d04-0410-961f-82ee72b054a4> Date: Tue Jul 4 10:22:56 2017 +0000 Use ucontext_t not struct ucontext in linux-unwind.h files. Current glibc no longer gives the ucontext_t type the tag struct ucontext, to conform with POSIX namespace rules. This requires various linux-unwind.h files in libgcc, that were previously using struct ucontext, to be fixed to use ucontext_t instead. This is similar to the removal of the struct siginfo tag from siginfo_t some years ago. This patch changes those files to use ucontext_t instead. As the standard name that should be unconditionally safe, so this is not restricted to architectures supported by glibc, or conditioned on the glibc version. Tested compilation together with current glibc with glibc's build-many-glibcs.py. Change-Id: I433dd983b8d18c538d96486f7362b953ece3bfb8
