Hi All, 

I get below qemu related warning when I build Tizen 3.0 common for armv7l. 

qemu: Unsupported syscall: 311 
qemu: Unsupported syscall: 311 
qemu: Unsupported syscall: 311 
qemu: Unsupported syscall: 311 
info: finished building perl-X11-Protocol 
info: finished building perl-Switch 

I use a 64-bit machine with 4G RAM.

There seems to be some compatibility issue with qemu and the kernel of Ubuntu 12.04LTS I am using. Some 311 numbered system call exptected by QEMU doesn't seem implemented. 

Is this harmful?? How to resolve this?
