Subject: [PATCH] Properly configure SQLite on Linux and OS X

Add all necessary -DHAVE_* flags that result from a run of the configure
script on Linux and OS X so that we build SQLite properly.  In particular,
this fixes mattn/go-sqlite3 #285 in which I spotted erratic backoff behavior
due to the lack of usleep support.
