fixed crash with dbg_fdt()

+ Apparently dbg_fdt() itself wasn't buggy, but for whatever reason GCC
  produced an absolute load to the prefix string in __print_prefix()
  which caused all the issues. Unclear why, seems like a compiler bug.

  This commit is more of a workaround, I'd still like to investigate
  this further.
