[Xen-devel] [PATCH] build: disable building kernel subsystem by default.

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

This support is obsolete and harks back to the days of out of tree Linux
kernel trees.

I think this could really be deleted entirely but for 4.3 lets just disable.
The list of kernels to build is empty by default anyway.

As well as George's release Ack this needs confirmation from Ian J that it
isn't going to confuse the test system.
