gcc: backport an upstream patch to make it work with newer glibc.

2018-04-24T21:30:04+00:00

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

    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.
