I'll give the patch a whirl in my regular bootstraps this weekend.
The Sun ld limitation is fixed in recent versions (at least Solaris 11,
perhaps also backported to S10) and I do have a patch to detect this and
turn off TARGET_SUN_TLS appropriately. Unfortunately, there's still a
corner case in 64-bit TLS-IE handling that isn't handled correctly, but
I haven't yet found to time to fully investigate this.
Thanks.
Rainer
