Actually, since the Linaro toolchain builds goal is to provide a 12
month lookahead on where upstream releases will be, I think it makes
sense for Linaro to do this switch early.  Since TI uses these
toolchains in our YP based builds, this mean that TI will likly be
working these issues ahead of adoption by OE.

However, neither TI nor Linaro can help with the issues related to PPC
(or MIPS if there are any).

I am sure we have reach the limit of discussion appropriate for the AB
list.  Real meat should be on the oe-core list as pointed out before.
