At least TC_FORCE_RELOCATION_SUB_SAME was introduced with Alan's
2002-09-05 patch. It is already in hjl's 2.13.90.0.16.

Now, thinking about debug info, AFAIK debug info doesn't contain
subtractions of global symbol and local one in the same section,
it always uses .L*-. etc. instead, so !S_IS_EXTERNAL
before !TC_FORCE_RELOCATION_SUB_SAME IMHO really
shouldn't hurt.
