Here's the patch I mentioned in
https://gcc.gnu.org/ml/gcc-patches/2019-01/msg01661.html
to work around an amd64 Solaris ld bug. I'm just posting it for
reference now: until it's clear if a fix will make it into Solaris 11.5
or not, there's no point in applying it yet.
Still, review comments are appreciated.
