In response to a change in binutils, commit b21ebf2fb4c
(x86: Treat R_X86_64_PLT32 as R_X86_64_PC32) was applied to
the linux kernel during the 4.16 development cycle and has
since been backported to earlier stable kernel series. The
change results in the failure message as below when rebooting
via kexec.
# kexec -l /boot/bzImage --append="console=ttyS0,115200 root=/dev/sda1"
Unhandled rela relocation: R_X86_64_PLT32
Fix this by replicating the change in kexec.

Hi,
FYI it is in master upstream as of b9de21ef51a7 so you could just
upgrade the recipe.
