Wenzong Fan 59106e5dce kernel.bbclass: build host programs with native sysroots
Allow to search header files and libs from native sysroots.

For example, an expanded BUILD_CFLAGS includes:
  '-isystem/builddir/to/linux-yocto/recipe-sysroot-native/usr/include'

And an expanded BUILD_LDFLAGS includes:
  '-L/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib
   -Wl,-rpath-link,/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib
   -Wl,-rpath,/builddir/to/linux-yocto/recipe-sysroot-native/usr/lib'

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 + qemuppc64)
  * 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.
