From ab05ea727942b5c1469e2e86548581264c6e2de4 Mon Sep 17 00:00:00 2001

Subject: [PATCH] gdbm: fix link failure against gcc-10
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.
Bug: https://bugs.gentoo.org/705898
