Sergei Trofimovich 884ebdc49c gdome2: fix build on -fno-common toolchains
Example of such toolchain is clang-12:

    $ nix-build -E 'with import ./. { }; gdome2.override { stdenv = clang12Stdenv; }'
    ...
    libgdome/xpath/gdome-xpath-xpnsresolv.c:33:
      multiple definition of `gdome_xpath_xpnsresolv_vtab';
      gdome-xpath.lo:libgdome/xpath/gdome-xpath-xpnsresolv.h:45: first defined here
