textproc/the_silver_searcher: -fno-common

Hi,

The following patch backport upstream patch to compile with
-fno-common :

https://github.com/ggreer/the_silver_searcher/commit/21eaa1c4160b868b0c5bbf59da17974429f30055

Upstream patch doesn't cleanly apply to src/search.c du to context
changes, but manually applying it work.

Tested with and without CFLAGS=-fno-common on amd64.

Comments or OK ?
