This doesn't really matter, but just to set the records straight:

I've been on with Ubuntu since Warty; but before then I used Gentoo.  I
KNEW I'd heard of this before... ;)

Note that guy is a developer.  Also I haven't seen --sort-common, I
wonder if it actually does anything... (--relax, one of the ones I
played with earlier, doesn't unless you're on some obscure
architecture).  -Wl,-z,combreloc looks interesting but the problem it
solves does not seem to be present so I assume that Ubuntu's build
server has that.

Hmm.  Interesting stuff. --as-needed looks neat too but some apps break
horribly :)
