Sorry I'm late.

This is for BSDs if anyone is interested:

* --hash-style=gnu doesn't work.
* --sort-common has no problems.
* -O1 makes a bit difficult (if not impossible) to obtain decent
backtraces while debugging certain things.



<unimportant side story>
While -O1 works just fine for everything I've tested so far, if
something fails and you want a backtrace out of a coredump or while
debugging a binary, you may only get the last call, everything else on
the stack is lost in 0xffffffff limbo.
I experienced this while debugging a stack overflow in Python's cPickle,
which could be the reason for this behavior (stack gone wild), but
removing -O1 made decent dumps/traces.
Of course I shouldn't have been debugging things with -Wl,-O1 in the
first place but oh well :+)
