gcc-linaro-6.3: Add patch for enable builds with glibc 2.26
The glibc 2.26 changed the struct ucontext to ucontext_t, this is a backported patch from oe-core. Tested building rpb-minimal-image for db410c. Change-Id: I2da06935aa2ba05c22260825eaf63ea4da17bb72 Signed-off-by: Aníbal Limón <anibal.limon@linaro.org>

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