bug#41726: vala-mitx2 test fails with gcc10

[Karl Berry]

Hi Andy - thanks for the report.

    /usr/bin/ld: baz.o:(.bss+0x0): multiple definition of `foo';
    bar.o:(.bss+0x0): first defined here

Looking at the sources in that test, it seems that the extern and the
initialization were mixed up. I don't have either vala or gcc10 readily
at hand. Would you be able to try this change, please?

To run just this one test, I think this incantation should do it (from
the top-level automake source directory, where you unpacked the tarball):
  make check TESTS=t/vala-mix2.sh

Thanks again,
Karl
