 >    Therefore, there are no in-tree defconfig that uses
 >    BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF.

 >  - In order to make the host openssl and host libelf usable by the
 >    Linux kernel build system, we had to ensure that HOST_CFLAGS and
 >    HOST_LDFLAGS were properly taken into account. This is done in
 >    patch 3.

 >  - Some defconfigs have a U-Boot that needs dtc on the host. For
 >    these, the fix is simple: add BR2_TARGET_UBOOT_NEEDS_DTC=y in the
 >    defconfig. Patches 14 to 22.

 >  - Finally, one defconfig, ts4900_defconfig, had a separate issue: it
 >    wasn't explicitly specifying a kernel version, causing a mismatch
 >    with the selected kernel headers version.

Committed all of these to 2018.02.x, thanks.
