    [gdb] Fix gdb build on mips64-linux
    
    When compiling for mips64-linux, we get:
    ...
    src/gdb/linux-nat-trad.c:139:12: error: ‘gdbarch_num_regs’ was not declared \
      in this scope
      139 |   regnum < gdbarch_num_regs (regcache->arch ());
    ...
    
    Fix this by including gdbarch.h in linux-nat-trad.c, similar to commit
    b1c896b365 "Fix gdb build on macOS".
    
    Build on mips64-linux.
