[Bug 2106408] Re: DEBUGINFOD_URLS not set in gdm

[Frank Ch. Eigler]

FWIW, this would be complicated, because the profile.d scripts construct
DEBUGINFOD_URLS (and related variables) by concatenating other .d style
files under /etc/debuginfod/.  pam_env's /etc/environment.* facilities
cannot do that, AFAIK.

  DEBUGINFOD_URLS not set in gdm

Bug description:
  After switching from lightdm (which sources /etc/profile) to gdm, gdb
  stopped offering debuginfod. Workarounds are SSH, TTY, and a manual
  `export DEBUGINFOD_URLS="https://debuginfod.ubuntu.com"`.
