[OE-core] [PATCH 1/1] conf/tune: add tune-ppce300c3

[Bruce Ashfield]

It has been pointed out several times that the yocto mpc8315e-rdb
reference was using the wrong tuning (603e), since it is actually
a e300c3 board.

This commit creates a e300c3 tune file based on the e300c2 variant
already in oe-core.

This commit also inhibits altivec in flac when this new tuning is
enabled. It was also noticed that the existing tune based overrides
in the flac package would not be triggered since DEFAULTTUNE is not
in the overrides list. To avoid doing per-board disabling of altivec
DEFAULTTUNE is added to the local package OVERRIDES and then used
to disable altivec.
