 >    BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL in patch 1.

 >    The qemu_x86_defconfig and qemu_x86_64_defconfig are however
 >    changed in a different way: by removing wireless support, which is
 >    the reason why host-openssl becomes necessary in recent kernel
 >    versions. Since Qemu doesn't emulate a wireless interface, it
 >    didn't make much sense to have this additional dependency. See
 >    patch 4 and 5.

 >    For all other defconfigs, we erred on the safe side, and kept the
 >    configuration as-is, and simply added
 >    BR2_LINUX_KERNEL_NEEDS_HOST_OPENSSL.

 >  - Some defconfigs have a Linux kernel that needs libelf on the
 >    host. Like host-openssl, we added a new option
 >    BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF. See patch 2.

 >    In practice, only qemu_x86_64_defconfig needed libelf and the host,
 >    and instead of bringing this dependency, we have disabled the ORC
 >    Unwinder from the kernel defconfig. See patch 4.

 >    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.
