Richard Purdie 7edd2be25f bitbake: utils: Handle lockfile filenames that are too long for filesystems 
The fetcher mirror code can go crazy creating lock filenames which exceed the
filesystem limits. When this happens, the code will loop/hang.

Handle the filename too long exception correctly but also truncate lockfile
lengths to under 256 since the worst case situation is lockfile overlap
and lack of parallelism.

(Bitbake rev: 315599b5b3ca0f1c797555db2460081681b6c945)

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.
