The command line to build a GCC for RTEMS contained virtually always a

This patch should be applied to GCC 4.9 branch and master.

Hmm the posix model is a little tricky. It would be good if this was the
standard for RTEMS however we know there are issues and leaving it
available lets us test when the issues start to get worked on yet having
this available also implies it is available for use. I suppose it is ok
and anyone building the tools knows what they are doing or is using
something like the RSB.
