[OE-core] HEADS-UP: Master now has GCC 4.9 as default

[Saul Wold]

Folks,

We have been testing with GCC 4.9 in master_under_test for sometime now 
and it's been passing local testing and sanity testing on the 
autobuilder.  Since we have the final fix for a PPC ICE issue in place 
now, we are moving to GCC 4.9 as the default in master for the 1.7 release.

Please be aware if this if you find some package failing unexpectedly.

Thanks to Khem and other for this effort!
