[OE-core] [RFC] .la files cleanup
Proposal: extend some bbclass with a task to remove unused .la files
Rationale: There are lots of recipes, which install tons of .la files
(thanks libtool),
but then do not ship them (correctly as most of them are unused in
real systems).
My proposal would be to include a special task or a
do_install_append() part that
will remove specified .la files. (like ${libdir}/xorg/modules/*/.la,
${libdir}/matchbox-panel/*.la, etc.). I see this usually done in
do_install or in special do_install_append
parts, but I think it would be better to handle this globally.

I think the simple append to the recipes concerned is just as simple as
any addition to core classes to try and do this generically...

I guess the ideal solution would be to find a way to stop libtool from
installing these things in the first place. It isn't totally obvious to
me that the .la files are a net benefit even for real shared libraries,
and for plugins I think they are probably a net loss in most/all cases.
When this issue last came up it seemed that Richard's preferred fix was
to just ship the .la files in FILES_${PN}-dev, and I guess that approach
does at least have the merit of simplicity. See:

I see... Then I'd drop some local patches dropping .la files and just
push them into -dev packages.
RP, is that suitable for you?

I also have this opinion. I think we need to experiment by not
installing .la at all and see what breaks. I would guess very little
