Would this solve it in your ports makefile (or is it too late to override?): CPUTYPE?=i586

That way the user can still set the CPUTYPE explicitly in /etc/make.conf to something better,
and we'd get a good default (i586 instead of i386). LLVM JIT generates code for pentium and above only, so if you really run it on a i386/i486 ClamAV won't
use LLVM's JIT (but fallback to an interpreter).

Please add back this code to libclamav/c++/bytecode2llvm.cpp while testing if CPUTYPE override works: #if !defined(LLVM_MULTITHREADED) || !LLVM_MULTITHREADED #error "Multithreading not available for llvm?" #endif

I think the problem is how FreeBSD's gcc is built. If gcc is built with i386-* triple, it will generate i386 code by default. Debian's is built as i486-linux-gnu. Anyway I don't think we can do anything about how gcc is built for old versions of FreeBSD.
