build: error at configure-time if WiMAX stack built with incompatible libnl (bgo #687630)

Browse source 
If the Intel WiMAX stack is built with libnl1, but NM is built with a
newer libnl, then symbol conflicts between libnl versions will occur
when the WiMAX plugin is loaded into NM, and NM will crash.

Distros should be building their WiMAX stack with libnl3, using the
following git repos, rather than the long-defunct Intel git repos:

git://people.freedesktop.org/~dcbw/wimax
git://people.freedesktop.org/~dcbw/wimax-tools

These repos contain fixes to allow the WiMAX stack to build against
libnl3.
