/sbin/prelink
Indeed, I think prelinking is the only solution for your case. Given the
statistics I posted on another email, the merging of libraries will not help a
lot since the number of relocations that disappear is small.
But note that ELF prelinking requires that the operating system supports it.
We know that Linux does, but you mentioned that you're using something
proprietary.
For me:
$ prelink -p | grep '^/.*Qt'
