1Backport and edit of patches from:
2https://gcc.gnu.org/viewcvs/gcc?limit_changes=0&view=revision&revision=249957
3by jsm28 (Joseph Myers)

5Current glibc no longer gives the ucontext_t type the tag struct
6ucontext, to conform with POSIX namespace rules. This requires
7various linux-unwind.h files in libgcc, that were previously using
8struct ucontext, to be fixed to use ucontext_t instead. This is
9similar to the removal of the struct siginfo tag from siginfo_t some
10years ago.
11
12This patch changes those files to use ucontext_t instead. As the
13standard name that should be unconditionally safe, so this is not
14restricted to architectures supported by glibc, or conditioned on the
15glibc version.
