[meta-freescale] meta-fsl-ppc - layer.conf issues

[Richard Purdie]

Hi,

I noticed that there is some "distro" policy creeping into
meta-fsl-ppc's layer.conf file, specifically:

BB_DANGLINGAPPENDS_WARNONLY ?= "true"

and

BB_ENV_EXTRAWHITE := "KSRC USRC"

The former is bad as it forces the policy for all layers. If the user is
expecting dangling appends to be errors, this hides potential problems
from them.

The latter forces the environment whitelist to a very specific set of
values. Both these things should not be present. 

As these force distro policy, I'd go as far as suggesting it threatens
Yocto Project Compatible status as its mixing machine and distro.

Please can we get these removed?

Cheers,

Richard
