This fixes a GCC warning that happens when compiling
gdb/compile/compile.c on some GCC versions (e.g., "gcc (GCC) 7.2.1
20180104 (Red Hat 7.2.1-6)").
It's a simple patch that converts "triplet_rx" from "char *" to
"std::string", thus guaranteeing that it will be always initialized.
I've regtested this patch and did not find any regressions. OK to
apply on both master and 8.1 (after creating a bug for it)?

* compile/compile.c (compile_to_object): Convert "triplet_rx"
to "std::string".
