sparse-0.5.0 won't link against lvm 3.5.0 as "llvm-config --libs" does not
include system libs like pthreads. This problem got fixed but not released
yet, so we need to fetch from their git repo.

This change does multiple things, all related to enable sparse usage as
a static analysis tool selectable from the OpenWrt configuration:
*add a KERNEL_SPARSE option in the config to add sparse to the kernel
build (through the C=1 option usage)
*add sparse as a new host tools. It will get selected automatically when
the above option will be enabled
