[yocto] multilib issue when setting DEFAULTTUNE

[McClintock Matthew-B29882]

All,

I'm having a problem building multilib for ppc64e5500. My local.conf
looks like this following:

require conf/multilib.conf
MULTILIBS = "multilib:lib64"
DEFAULTTUNE_virtclass-multilib-lib64 = "ppc64e5500"

If I change the last time to:

DEFAULTTUNE_virtclass-multilib-lib64 = "powerpc64"

Everything works just fine. We get images built, sysroot created, etc

Obviously we want the first one to work as it has additional compiler
flags for that target. I've tried tweaking tune-ppce5500-64b.inc to
look like arch-powerpc64.inc almost exactly but I'm really just
guessing here...

What happens is bitbake essentially locks up if I enable -DDD the
output will usually look something like this:

DEBUG: LOAD /local/home/mattsm/git/poky/meta-yocto/recipes-core/netbase/netbase_4.45.bbappend
DEBUG: BB :0: inheriting classes/multilib.bbclass

And freeze, the last class it freezes on could be one of several but
the multilib.bbclass is always close to being the last one loaded.

Does anyone have any pointers about where to start looking?
