[Rd] [PATCH] Makefile: add support for git svn clones

[Karl Millar]

Fellipe,

CXXR development has moved to github, and we haven't fixed up the build for
using git yet.  Could you send a pull request with your change to the repo
at https://github.com/cxxr-devel/cxxr/?

Also, this patch may be useful for pqR too.

Thanks
