That patch was not applied because -fno-merge-debug-strings was
implemented instead.

`-fno-merge-debug-strings'
     Direct the linker to merge together strings which are identical in
     different object files.  This is not supported by all assemblers or
     linker.  This decreases the size of the debug information in the
     output file at the cost of increasing link processing time.  This
     is on by default.

That change fixes the problem by making whether a debug section is
mergeable independent of the optimization setting.  It is in gcc 4.3 and
later.
