linux-libc-headers-yocto: disable device tree generation

Richard/Saul,

This fixed the error picked up overnight where the libc-headers fails because there is no dtb to install.

Note: this could have been fixed by factoring out the include of linux-dtb.inc into the individual recipes rather than by modifying the libc-headers rule to set the KERNEL_DEVICETREE to nothing. But the libc-headers is the exception and most any other recipe that includes linux-yocto.inc needs this enabled, so I opted to leave the includes as they were.

Pull URL: git://git.pokylinux.org/poky-contrib.git
Branch: zedd/kernel
Browse: http://git.pokylinux.org/cgit.cgi/poky-contrib/log/?h=zedd/kernel

Thanks,

Fixes [BUGID #719]

The common routines for handling a git based yocto kernel are included from the lib headers recipe to checkout the appropriate branch of the kernel for header generation.

linux-yocto.inc includes device tree installation rules which typically apply to a kernel user of the include file, but do not apply to a simple header generation. The fix is to override the DTB variables in this recipe, which disable the device tree installation rules.

Merged to master, thanks.
