Avoid 64-bit Solaris/SPARC -gstabs link failures (PR ld/12152)

But this choice was made more than a decade ago (not by me).  What's the point 
in reversing it in 2012, where nobody should be caring about STABS for long?
SPARC or Solaris guys have other things to do than dealing with gratuitous 
incompatible changes.  And the program is not invalid, just the debug info.
