[meta-ti] [PATCH 1/5] linux.inc: If the kernel has CONFIG_KERNEL_LZO=y, it may well attempt to use the 'lzop' utility to do the lzo compression, but we should not be relying on that utility being installed on the build machine.

[Koen Kooi]

From: Christopher Larson <chris_larson at mentor.com>

This currently affects the linux-omap4 build for omap4430-panda.
