In the win32 gitian descriptor the C*FLAGS are being overridden on configure, which causes the built-in optimization flags to be removed. Add -O2 manually (but not -g as we're doing nothing with the debug information).
Improves performance of win32 gitian builds.
As a bonus, fixes issue #3494 (see this comment: #3497 (comment) ).

Automatic sanity-testing: PASSED, see http://jenkins.bluematt.me/pull-tester/0d512a9ee7f01dbd6c06e83c2b3321d185790184 for binaries and test log. This test script verifies pulls every time they are updated. It, however, dies sometimes and fails to test properly. If you are waiting on a test, please check timestamps to verify that the test.log is moving at http://jenkins.bluematt.me/pull-tester/current/ Contact BlueMatt on freenode if something looks broken.
-O2 is really needed three times and with the link flags?
Yes. It can't hurt anyway.
What? We were building win32 binaries without any optimization?
Yes. But only after the autotools switch. We never did an actual release that way.
