specify the cpu type for LLVM for OpenBSD target
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 #20777, "x86-64" is the right thing to do for x86_64 builds. Closes: #31363
