Where have you got your toolchain from?

It's hopelessly outdated. The current rtems-4.10 toolchain consists of
gcc-4.4.7 + newlib-1.18.0

Or is there are typo in your initial sentence?
Did you mean newlib-1.16.0 instead of newlib-1.6.0?

This could indicate you are trying to use an rtems-4.9 toolchain to 
build rtems4.10 - This doesn't work. Building rtems-4.9 and rtems-4.10 
need different versions of the toolchains.
