[OE-core] icecc in OE (Was: [PATCH] icecc.bbclass: prevent nativesdk builds depending on target specific KERNEL_CC)

[Martin Jansa]

Hi Tomas,

last time we were more actively using 1.0.1-1 (with Ubuntu 12.04), but
nowadays icecc.bbclass is mostly just historic relic for us, we still
inherit it in our DISTROs (with 99.9999% builds running with ICECC_DISABLED
= "1"), so that if someone enables icecc again he will get the same sstate
signatures as our jenkins builds - to reuse already prepopulated
sstate-cache.

We also use own version of icecc-create-env, still the same as long time
ago in:
https://github.com/openwebos/meta-webos/tree/master/recipes-upstreamable/icecc-create-env

Regards,
