Re-evaluate mirrors on our GitHub
Summary
We have several mirrors on our GitHub located at https://www.github.com/RTEMS/
- https://github.com/RTEMS/gnu-mirror-gcc
- https://github.com/RTEMS/sourceware-mirror-binutils-gdb
- https://github.com/RTEMS/sourceware-mirror-newlib-cygwin
Motivations for moving these:
- It's confusing on our GitHub page
- We now have GitLab if we need to run our own patches it would be easier if we mirror it there so we can fork it.
- At least GCC has their own official GitHub mirror now and the other two are small.
