qemu: Add "-Wno-error" flag to qemu target

GCC 5 and above fails to build OP-TEE project under QEMU.
Warnings are now treated as errors by default.

On line 60 --extra-cflags="-Wno-error" fixes the issue.
Please reference
[OP-TEE/optee_os#550](https://github.com/OP-TEE/optee_os/issues/550) for
specifics.

My machine is running gcc version 5.2.1 20151010 and I can confirm this
now works with change. It affects both default.xml and default_stable.xml repo
configurations for OP-TEE.
