I see what you want to do. The subject was a little confusing. You  
would do this:

./configure --target-list=i386-softmmu

You could also do this:

./configure --target-list=ppc-softmmu,i386-softmmu

Most likely these are functions or variables that are not defined in  
QEMU. Maybe you are missing a header file.
