Title:
  kexec fails with "Unhandled rela relocation: R_X86_64_PLT32"

Status in kexec-tools package in Ubuntu:
  Fix Committed
Status in kexec-tools source package in Bionic:
  Invalid
Status in kexec-tools source package in Cosmic:
  Fix Committed

Bug description:
  [Impact]
  Without this fix, kexec won't be able to load kernels on amd64.

  [Test Case]
  kexec has been tested to be able to load a 4.18 kernel.

  [Regression Potential]
  As the fix is only applied to the x86_64 portion of kexec, only this platform should be affected. Package with fix has been tested there.

  
  When running kexec with 4.18, it fails.

  $ sudo kexec -l /boot/vmlinuz-4.18.0-5-generic --initrd /boot/initrd.img-4.18.0-5-generic --append "`cat /proc/cmdline`"
  Unhandled rela relocation: R_X86_64_PLT32
