[oe] [PATCH] 500+ recipes: remove do_stage

[Bernhard Reutner-Fischer]

Hi,

i'm seeing this:
ERROR: This recipe recipes/libidl/libidl_0.8.3.bb) has a
do_stage_prepend or do_stage_append and do_stage now doesn't exist.
Please rename this to do_stage()

given that only preferred-om-2008-versions.inc pins this to a specific
version (0.8.10) i'd remove the "broken" version and .2 too, while at
it:
$ git rm recipes/libidl/libidl*0.8.{2,3}.bb && git commit -s -m 'libidl:
Remove old versions' recipes/libidl/
