[OS-BUILD PATCHv3 3/3] kernel.spec.template: Add global compression variables

[Prarit Bhargava (via Email Bridge)]

From: Prarit Bhargava <prarit(a)redhat.com&gt;

kernel.spec.template: Add global compression variables

Add global compression variables.  'compression' is the compression
utility, and 'compext' is the compression extension.  In the case of xz,
these variables have the same value but that may not always be the
case.
