Konrad Weihmann 17b80b70ba file: add PACKAGECONFIG for auto options
A few options of file configure are set to auto, which can lead to
unpredictable effects when something in the sysroot does provide
things that satisfy the autotools checks.
In the worst case this will lead to package-qa failures as libraries are
not set in RDEPENDS but configured for the tool.

To mitigate changes of accidental configure set explicit options via
newly introduced PACKAGECONFIG variables for bzip, lzma and zlib
support, where the default is just zlib, as it was before

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.
