Reset poky to before our libpam hacks

Things got a bit out of synch with openbmc-config due to the libpam
issues and the migration from the meta-* layers.

Revert the two previous commits and then put the latest poky in with the
libpam revert and get openbmc-config right again.

Revert "Revert "libpam: update 1.3.1 -> 1.5.1""

This reverts commit 87ddd3eab4df68e624b5350ccaab28b3b97547c0.

Revert "poky: subtree update:796be0593a..10c69538c0"

This reverts commit c723b72979bfac6362509cf1fe086900f6641f28.

+Subject: [PATCH] gdbm: fix link failure against gcc-10
+
+Copied from gentoo's solution at https://bugs.gentoo.org/show_bug.cgi?id=705898
+Original patch by Sergei Trofimovich <slyfox@gentoo.org>
+
+Original description:
+
+Before the change on gcc-10 link failed as:
+```
+  CCLD     gdbmtool
+ld: ./libgdbmapp.a(parseopt.o):(.bss+0x8): multiple definition of `parseopt_program_args';
+  gdbmtool.o:(.data.rel.local+0x260): first defined here
+ld: ./libgdbmapp.a(parseopt.o):(.bss+0x10): multiple definition of `parseopt_program_doc';
+  gdbmtool.o:(.data.rel.local+0x268): first defined here
+```
+
+gcc-10 will change the default from -fcommon to fno-common:
+    https://gcc.gnu.org/PR85678.
+
+The fix is to avoid multiple definition and rely on
+declarations only.
