Backport !3009 “gtimezone: Fix symlink checks on relative link targets” to glib-2-74
requested to merge pwithnall/glib:backport-3009-timezone-relative-link-target-glib-2-74 into glib-2-74
The changes in 6265b2e6 to reject weird
/etc/localtime configurations where /etc/localtime links to another
symlink did not consider the case where the target of /etc/localtime
is a relative path. They only considered the case where the target is
absolute.
Relative paths are permissible in all symlinks. On my Fedora 36 system,
/etc/localtime’s target is ../usr/share/zoneinfo/Europe/London.
Fix the check for toolbx by resolving relative paths before calling
g_lstat() on them.
