cannot cross compile with sqlite support

First, thanks for sql-migrate. It's a great tool. We have been using it so far with success inside docker containers, but because sqlite can't cross compile, we've had to write custom mains (using sql-migrate in library form without sqlite included). Is there possibly some strategy (besides just forking and commenting out sqlite) that could be used to allow cross compiles of the main sql-migrate program when we don't need sqlite support. I'm compiling from mac. See also https://github.com/mattn/go-sqlite3/issues/384

Example of failed compile:

GOOS=linux GOARCH=amd64 go build -o casey-test sql-migrate/*.go
# github.com/mattn/go-sqlite3
../../mattn/go-sqlite3/sqlite3_go18.go:18: undefined: SQLiteConn
../../mattn/go-sqlite3/sqlite3_go18.go:26: undefined: SQLiteConn

../../mattn/go-sqlite3/sqlite3_go18.go:63: undefined: SQLiteStmt
../../mattn/go-sqlite3/sqlite3_go18.go:36: too many errors

We don't actually use sqlite and if you comment out this line below, the cross compile works.

Start with sql-migrate/config.go and reproduce the reported GOOS=linux GOARCH=amd64 build command from the issue. Determine how the main program can be built without requiring SQLite support, while preserving SQLite use when needed; done means the cross-compilation command succeeds without commenting out the driver import.
