sparc tools do the same, and 2) Place the patch at rtems-tools as Dr. Joel
mentioned and refer to it from RSB.

I think RTEMS would prefer the second approach to avoid fetching from
external sources that might be changed or even the URL might get
invalidiated, seizing the whole toolchain build (and IIRC that happened
with sparc)
