indeed. I don't have the time to try Illumos derivatives myself, but
looking closer that -z relax=transtls was neither in OpenSolaris (and
thus isn't in Illumos either) nor in Solaris 11.0. Must have been
introduced at some later point, but it's certainly present in Solaris
11.3, the oldest version I can easily try.
There are two options here:
* Either Illumos has already fixed the ld bug worked around by -z
transtls. Then the absence of the option doesn't matter and things
will work fine.
* Otherwise (and independently of the Illumos situation) I'll add a
check for Solaris ld supporting the option instead of using it
unconditionally.
