I took the updated gold ( b8cf50755b57314), compiled opendkim -flto with both
gold and ld and compared the sizes:
471664 - bfd
475896 - gold
So gold/master still produces bigger binaries than bfd (with -Wl,-s).
Moreover, stipping (with strip/master) the bfd binary does not change the
binary, whereas stripping the gold binary, modifies the result. `readelf
--all` on both stripped and unstripped gold binary returns:
--- stripped 2015-06-07 22:04:47.058504804 +0000
+++ unstripped 2015-06-07 22:04:53.566504302 +0000
