Issue installing a GNAT cross-compiler

[Joel Sherrill]

It will also help to have a new enough RTEMS and tools where the network
headers are in the C Library. They were moved to make building tools which
needed networking headers easier.

Our general push is to get most/all of the POSIX headers packaged with the
C Library even if the implementation is in RTEMS. This makes the headers
available when building the tools. There is a chicken and egg problem when
building the tools for RTEMS for some .h files.
