Subject: [PATCH] linux: add BR2_LINUX_KERNEL_NEEDS_HOST_LIBELF
Some Linux kernel configuration options (such as CONFIG_UNWINDER_ORC)
require building a host program that needs libelf.
Users who have libelf installed on their system won't see a problem,
but users who don't have libelf installed will get a build
failure. Therefore, this commit adds an option that allows a user to
indicate that his Linux kernel configuration requires libelf. When
this option is enabled, we add host-elfutils to the dependencies of
the linux package (host-elfutils provides the libelf library).

+ Some Linux kernel configuration options (such as
+ CONFIG_UNWINDER_ORC) require building a host program that
+ needs libelf. Enabling this option will ensure host-elfutils
+ (which provides libelf) gets built before the Linux kernel.

+ CONFIG_UNWINDER_ORC=y, please install libelf-dev,
+ libelf-devel or elfutils-libelf-devel".
