[Virtio-fs] [PATCH 1/5] build-qemu: Add support for ppc64le

[Fabiano Rosas]

Allow running the script on a ppc64le machine to build a ppc64le QEMU
binary.

The configuration differs from x86 in the following:

--enable-fdt:
We need to build with device-tree support because ppc relies on it.

--enable-tcg:
The ppc build without TCG is currently broken.
