Title:
  questing: FTBFS on ppc64el in questing proposed with LTO enabled

Status in lto-disabled-list package in Ubuntu:
  Fix Released
Status in nvidia-cuda-toolkit package in Ubuntu:
  New

Bug description:
  Since 12.3.2-1 and currently with 12.4.1-2 in questing proposed,
  nvidia-cuda-toolkit FTBFS on ppc64el with LTO enabled.

  This is currently preventing migration of 12.4.1-2 to the questing
  release pocket, and will for the upcoming Qt 6.9 transition block that
  transition due to the required rebuild not being migratable.

  Upon testing, adding nvidia-cuda-toolkit to the lto-disabled-list for
  ppc64el resolves the FTBFS

  Obviously it is ultimately desirable that the package builds
  successful with OR without LTO.

  The original build error is:
