We have more than one member that lists living in the same city as the O.P - perhaps someone **could** go look over their shoulder.
@O.P. - -
The specific information that Hawhill requests above would be a good starting point for answering your question.
Note:
The gcc/g++ toolchains generally available are **not** built with the defaults set to match the i.MX6 as used in the Kindles.
Not even Freescale's toolchains.
So unless the O.P. built this toolchain their self ....
(Highly unlikely)
