A freestanding GCC does, but for toolchains targeting an OS, a toolchain
is more than just GCC. 

In general, such a toolchain consists of a compiler + a system's runtime

In case of RTEMS, this runtime environment consist of newlib+rtems,
in case of linux this would be the kernel+glibc.

It is more than just cross-compiling GCC. It is building/bootstrapping
an OS.
