Andrei Gherzan 9cc9232e31 qemu: Define libnfs PACKAGECONFIG
The upstream qemu recipe uses host's pkg-config files as a solution to
detecting host's SDL. This has a side effect of using other host
libraries that are later queried by the configure script. This can get
into a situation when the host provides libnfs (for example) and because
later this dependency is not in place anymore, qemu will fail at
runtime.

This change adds a PACKAGECONFIG definition for libnfs that is disabled
by default, in turn disabling the pkgconfig autodetection in configure.

QEMU Emulation Targets
======================

To simplify development, the build system supports building images to
work with the QEMU emulator in system emulation mode. Several architectures
are currently supported in 32 and 64 bit variants:

  * ARM (qemuarm + qemuarm64)
  * x86 (qemux86 + qemux86-64)
  * PowerPC (qemuppc only)
  * MIPS (qemumips + qemumips64)

Use of the QEMU images is covered in the Yocto Project Reference Manual.
The appropriate MACHINE variable value corresponding to the target is given
in brackets.
