[yocto] Yocto 2.2 minimum kernel requirement

[Vuille, Martin (Martin)]

I should clarify that these build machines are not for Yocto builds,
but for building an application that uses the Yocto SDK.

Subject: [yocto] Yocto 2.2 minimum kernel requirement

We are looking at upgrading from Yocto 1.8 to 2.2.

Yocto 2.2 has a minimum kernel requirement of 3.2.0.

This isn't an issue for our target (ARMv5, Linux 4.4) but may be
an issue for our automated build machines (x86, Linux 2.6.32-CentOS 6.)

However, there is a note that says
"For x86 and x86_64, you can reset OLDEST_KERNEL<https://urldefense.proofpoint.com/v2/url?u=http-3A__www.yoctoproject.org_docs_2.2_mega-2Dmanual_mega-2Dmanual.html-23var-2DOLDEST-5FKERNEL&d=DQMFAg&c=BFpWQw8bsuKpl1SgiZH64Q&r=SbT_XjBLTrjzWy1iRhblzG3bKRhcodBp7tD_mnp1dpg&m=JBfbjyLEHgQmBZGcIm8lb9q00p7ApivpoxD9UIz8BE0&s=UevjhjTvolaxefVicfpOrA5-ShXGU7YBHo7bUeDG3OQ&e=> to anything down to 2.6.32 if desired."

Is it possible to configure things such that we can keep supporting the old
kernel for the SDK while we support a more up-to-date kernel for the target?
