cortexa53-crypto: missing sstate manifest when building nativesdk

[fhoerni-w]

When I build for target and nativesdk in the same direcory I get a build error, like this:

$ bitbake cpio

I noticed that DEFAULTTUNE is not the same for target and nativesdk builds (cortexa53-crypto vs cortexa53), and this may be a reason for the error.

What would be the best approach to fix this:

• fix something in meta-freescale?
• fix something in my project layer? (DEFAULTTUNE="cortexa53-crypto" or PACKAGE_EXTRA_ARCHS:append:class-nativesdk = " cortexa53-crypto")

The second options does fix the issue, but I suppose others might be concerned, and might be interested by a wider fix.
