This is very much insufficient.  Try --target-list=i386-softmmu and watch it fail to link.
You need to modify the build rules to make certain that the loongarch disassembler is 
built for loongarch host.

I realized that "target/loongarch/disas.c" is only used for loongarch 
target . When the target is not "loongarch", the function 
"print_insn_loongarch" will not be compiled. Next I will add loongarch 
support to "disams/*".


Thanks.

More specifically, this is adding support for disassembling
on LoongArch hosts. The handling of disassembling LoongArch
guests is already connected up.

thanks
