linux: add support for linux26-{menuconfig,xconfig,gconfig} targets

Browse Source 
These targets allow the user to customize the configuration of the
Linux kernel. After changing the kernel configuration, the next time
the user runs "make", the kernel is rebuilt to take into account the
new configuration (not rebuilt from scratch).
