GCC 10?  That has apparently changed how multiple symbols defined in
different sources are dealt with by default, try adding -fcommon to the
build flags to ld/gcc.

The old way was to merge all instances of a global variable if they all
agreed on initial value (or lack of one).

Somebody will probably want to go through each global and tidy this up.
