Update GDB on RTEMS 5

Summary

On multiple host OSes with newer GCC or LLVM, the gdb used in the RTEMS 5 tools no longer builds. The failure varies based on the RTEMS target and host. On some hosts, the build failure is in a simulator while others fail elsewhere.

FreeBSD 14 fails with this:

There are other odd issues like a simulator build issue with the v850 that shows on some hosts.
