I got rid of the @progbits/%progbits differences in the assembly, as
well as the .cpu and .arch differences,
but still observe the same failure.

Title:
  arm64: "unsupported RELA relocation"

Status in gcc-5 package in Ubuntu:

Bug description:
  linux-image-4.3.0-5-generic 4.3.0-5.16 arm64 fails to load modules
  (and therefore boot). It emits messages like the following for each
  attempted module load:

  [    2.156817] module libahci: unsupported RELA relocation: 275

  This is reminiscent of LP: #1502946 - except that fix appears to still
  be in-tact. What has changed, however, is the build environment. If I
  rebuild the same kernel source in a wily chroot, it boots fine.

  Marking "Confirmed" because Paulo Pisatti reported this to me, and I
  reproduced.
