The initial purpose is to workaround the LLVM bug https://llvm.org/bugs/show_bug.cgi?id=26554 for OpenBSD. By default, the `cpu' is defined to `generic`. But with a 64bit processor, the optimization for `generic` will use invalid asm code as NOP (the generated code for NOP isn't a NOP). According to rust-lang#20777, "x86-64" is the right thing to do for x86_64 builds. Closes: rust-lang#31363

A quick fix for several issues that break a Solaris/Illumos build. Also, adds a CPU target specification (as seen in a patch for OpenBSD #31727).
