Split compile and link for MinGW support
MinGW test_jit fails with no error message. Perhaps linker flags should
not be passed when compilation is happening.

Anyway splitting these stages doesn't matter for performance. So let me
just split it to fix the issue. Probably this helps Solaris's issue too.
