gnupg2 still tries to run test even if it tries to avoid it in
cross-compilation.
Really disable running the tests.
Since that requires a complete autoreconf, the existing patch against
configure is turned into a patch against the m4 macro.
since we autoreconf, we slightly patch configure.ac to not emit git
errors on stderr because it is not in a git tree.
[Thomas: rename patch 0000 to 0004, as suggested by Arnout.]
