Title:
  please export the data for the elf package metadata in the env

Status in dpkg package in Ubuntu:
  Fix Released

Bug description:
  starting with 24.10, dpkg now passes in dpkg-buildflags

    -specs=/usr/share/dpkg/elf-package-metadata.specs

  and specifying the package metadata json string in the specs file.
  This currently only works with GCC and not other compilers.  To have
  quicker adoption for more binaries, please also export that
  preformatted string in an environment variable ELF_PACKAGE_METADATA,
  that can be picked up by other linkers and compilers.

  choosing a deb-packaging neutral name for that enivronment variable,
  because it potentionally could be useful to embed such information
  into snap builds as well.
