[patch 0/2] dmapi: build system revamp

[Ben Myers]

Hi,

Here are Jan Engelhardt's patches originally posted here
http://oss.sgi.com/archives/xfs/2012-05/msg00323.html
as they apply to dmapi.  

Patch 2 applied without much modification, patch 3 was not necessary for dmapi,
and patch 6 did not apply at all so I implemented that.

Regards,
	Ben
