at91bootstrap: upgrade to 3.10.3

[joelguittet]

The purpose of this Pull Request is to fix the "-nostartfiles" issue reported here: #254

I'm upgrading to 3.10.3. Please note 3.10.4 is also available but another issue appears with it so I prefer to keep this one.

Hello @joelguittet

Thanks for your contribution.

We have upgraded our AT91Bootstrap to 4.0.6 in our last Linux4Sam 2023.04 release. You can see the release notes in the URL below. We will be removing support for older versions in the next release and hence I have to drop this PR. So I kindly recommend you to migrate to our latest release.

Hello @gehariprasath
My understanding was the at91bootstrap was not compatible with all machines, particularly the old ones. I m wrong maybe ? Can you confirm the 4.x versions are not limited to recent processors ?
Thanks

EDIT: just checked and tried to build it. My machine is at91sam9x5ek and this is not compatible with the list in the 4.0.6 at91boostrap recipe. Error is the following:

ERROR: at91bootstrap-4.0.6+gitAUTOINC+d166742ae1-r0 do_configure: No config files found

@gehariprasath gentle ping! :-)
It's annoying to not have the old at91bootstrap, or something need to be updated in the 4.x releases.
Or maybe the strategy of meta-atmel is not to maintain the 3.x at91bootstrap, and I have to keep it in my own layer ? If so, not a problem for me.

Hi @joelguittet,
Yes, we are planning to remove the support for old at91bootstrap and you can keep it on your own layer.

Hello @joelguittet

Apologies for the delayed response. Yes I was about to tell you that you have to maintain the support for older version of at91bootstrap in your custom layer. We discussed internally and it's our policy to remove support for older versions of AT91Boostrap when we usually migrate to a new Yocto project version.

Closing #254 at the same time.
