linux: remove support of linux26-* targets

The linux-* mirror targets of linux26-* have been added a very long time ago
(2010) and linux 2.6 is now considered 'old' anyway. It no longer makes
sense to support these linux26-* targets, so this patch removes them.

This is a simplification introduced in preparation of the kconfig-package
infrastructure.
