gdbm: add patch to fix link failure against gcc 10
This also makes appending "-fcommon" to CFLAGS obsolete and enables native builds with a host gcc v10. Signed-off-by: Richard Leitner <richard.leitner@skidata.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

+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.
+
