Also added c-ares library recipe.
In libcurl there is an issue with DNS lookups that cause crash on some platforms:
http://curl.haxx.se/mail/lib-2008-09/0197.html
To avoid this issue libcurl has to be built with c-ares name resolver.

I am still considering this patch, but need to understand what platforms
curl is failing on.

Additionally, if adding this to oe-core, it needs to be in it's own
patch crediting the orignal author / layer, I found a 1.10 version in
the meta-webos-ports, is this where it came from?

This is why I wanted to understand the orignal failure, so using
PACKAGECONFIG sounds reasonable, I think we have had a case in the past
where we even allowed for a non-default PACKAGECONFIG point outside of
oe-core (I can't remember which one it was now).

There is a c-ares recipe in oe-classic which looks quite similar to this
one and I suspect that's probably where it came from (though perhaps
indirectly).
But, configuring curl to use c-ares support is not as trivial a change
as it might appear and there is a significant chance that it will cause
unforeseen (and probably unwanted) effects for at least some people.
Adding a PACKAGECONFIG option for it which defaults to off would
obviously be fine, and changing the default to be the libcurl internal
threaded resolver (which would probably fix the original complaint as
well, and doesn't require any extra recipes) might also be fine, but
enabling c-ares by default is not something that should be done
capriciously.

As far as I've tested curl crashes on i386, cedartrail and x86-64 platforms.
The c-ares recipe was borrowed from meta-webos-ports.
I'll prepare new version of this patch that will include PACKAGECONFIG
switch.
Best regards,

I think having c-ares in oe-core would be a splendid plan, actually.
But I don't think that making curl use it by default is a good idea.
