Adding fetch.type git as a variant?

[David Bruce]

Hi,

> Agreed. I meant to suggest a new t4k_common-devel port to use the authors SCM system.

This thread clears things up a lot - looks like a separate *-devel
port is the recommended way to support building from git, rather than
a variant.  I'll test that out locally and submit it for potential
inclusion when it works as intended.

Thanks,
