Chris Laplante via bitbake-devel 7278f3f786 bitbake: bb.utils.fileslocked: don't leak files if yield throws
Discovered with a recipe under devtool. The ${S}/singletask.lock file (added by
externalsrc.bbclass) was leaked, giving a warning like:

  WARNING: <PN>+git999-r0 do_populate_lic: /home/laplante/yocto/sources/poky/bitbake/lib/bb/build.py:582: ResourceWarning: unclosed file <_io.TextIOWrapper name='/home/laplante/yocto/build/workspace/sources/<PN>/singletask.lock' mode='a+' encoding='UTF-8'>

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.
