Subject: [PATCH] Not finding pkg-config shouldn't be fatal on OS X.

pkg-config is usually not installed on OS X machines. Before this change:

    $ go run make.go
    No pkg-config found. Can't determine whether sqlite3 is available, and where.
    exit status 1

Now:

    $ go run make.go
    SQLite not found. Either install it, or run make.go with --sqlite=false
    On OS X, run 'brew install sqlite3' and set PKG_CONFIG_PATH=*snip*
    exit status 2
