Ralf covered the build tools so I will cover the "c tools" part.
Since RTEMS is a embedded RTOS and developed using cross compilation,
you have to have a compiler which produces the right target code.
On top of that, there are differences between the various 
canonical targets even if the underlying CPU family is the same.
For example, i386-netbsd and i386-rtems are similar to and share
source code with i386-linux but there are target OS differences
which result in the toolsets being different.
