Robert Yang c85bca39db ccache.bbclass: Set CCACHE_TEMPDIR
Fixed when build with buildtools-tarball:

$ bitbake linux-libc-headers
  HOSTCC  arch/x86/tools/relocs_common.o
  ccache: error: Failed to create directory /run/user/0/ccache-tmp: Permission denied

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.
