[meta-virtualization] Dev86-native dependency

[Sathees Balya]

Thanks Mark and Chris.

I applied the patch from Chris and was able to build for arm.

Also, as Mark said bitbake -e xen returned the following for the OVERRIDES with the aarch64.

OVERRIDES="linux:aarch64:pn-xen:fvp:aarch64:poky:class-target:libc-glibc:forcevariable"


Regards,
Sathees

    Does XEN_TARGET_ARCH ever actually deviate from TARGET_ARCH? I do
    prefer using the overrides as it tends to be overall more clear to
    read, but the will work too.

    Sathees, there isn't much to the overrides, do a 'bitbake -e xen' and
    pipe the output to a file. Then search for "OVERRIDES" and you should
    find a list of override words, appending one of these words to a
    variable such as DEPENDS will only set the assignment if the override
    is present. Read a few tutorials and examine some examples and you
    should be able to sort it out rather quickly.
