[patch] comment: push_target: Fix comment

[Jan Kratochvil <jan.kratochvil@redhat.com>]

Hi,

I would like to update this comment but I was told one should not make
references to other code in comments as such comment may become stale.
OTOH unaware how to fix it otherwise, changing this code will most probably
require updating the referenced add_target_sections code anyway.


Thanks,
Jan
