commit a5359ddd05 upstream.
GCC 10+ defaults to -fno-common, which enforces proper declaration of
external references using "extern". without this change a link would
fail with:
lib/raid6/test/algos.c:28: multiple definition of `raid6_call';
lib/raid6/test/test.c:22: first defined here
the pq.h header that is included already includes an extern declaration
so we can just remove the redundant one here.
