gcc-10 changed the default from -fcommon to fno-common:
  https://gcc.gnu.org/PR85678

As a result build fails as:

    ld: dfa.o:/build/gnugo-3.8/patterns/../engine/liberty.h:861: multiple definition of
      `meaningless_white_moves'; mkpat.o:/build/gnugo-3.8/patterns/../engine/liberty.h:861: first defined here
    ld: dfa.o:/build/gnugo-3.8/patterns/../engine/liberty.h:860: multiple definition of
      `meaningless_black_moves'; mkpat.o:/build/gnugo-3.8/patterns/../engine/liberty.h:860: first defined here

The change moves variable definitions into a single .c file that uses them.
