[PATCH] gdbm: add patch to fix link failure against gcc 10

[PATCH] gdbm: add patch to fix link failure against gcc 10

[Richard Leitner]

This also makes appending "-fcommon" to CFLAGS obsolete and enables
native builds with a host gcc v10.

+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.

Series: gdbm: add patch to fix link failure against gcc 10
Revision: 1
URL   : https://patchwork.openembedded.org/series/23952/
State : failure

== Summary ==


Thank you for submitting this patch series to OpenEmbedded Core. This is
an automated response. Several tests have been executed on the proposed
series by patchtest resulting in the following failures:



* Issue             Added patch file is missing Upstream-Status in the header [test_upstream_status_presence_format] 
  Suggested fix    Add Upstream-Status: <Valid status> to the header of meta/recipes-support/gdbm/files/gdbm-fix-link-failure-against-gcc-10.patch
  Standard format  Upstream-Status: <Valid status>
  Valid status     Pending, Accepted, Backport, Denied, Inappropriate [reason], Submitted [where]



If you believe any of these test results are incorrect, please reply to the
mailing list (openembedded-core@lists.openembedded.org) raising your concerns.
Otherwise we would appreciate you correcting the issues and submitting a new
version of the patchset if applicable. Please ensure you add/increment the
version number when sending the new version (i.e. [PATCH] -> [PATCH v2] ->
[PATCH v3] -> ...).
