Link error on Solaris 11.3 sun4v sparc

[Rees Machtemes]

I'm trying to build Global on Solaris 11.3 on SPARC. It fails with
this link error, but appears to be using built-in libtdl, not the
installed libtdl from Solaris. I have some experience porting and
building packages on Linux and BSD, but not this OS. Am I the first to
try on 11.3?
