 Just for the record, I've reverted this.

 Reportedly even gdb 7.1 is not new enough for this, and moreover while this 
in theory is supposed to make gdb faster and use less memory, in practice the 
handling in gdb seems to have problems that actually make gdb slower and use 
more memory.

 The flag may be still useful for people who want smaller binaries and don't 
use gdb for much more than backtraces, but it's apparently not a good default 
for the time being.
