In out-of-tree builds gtk-doc's setup-build target copies all the content from $srcdir to $builddir. However, if some of this content is regenerated at configure time this can happen: 1) configure writes new build/version.xml 2) make compile copies content, including the tarball's src/version.xml to build/version.xml, and generates gtk-doc. 3) make install notices build/version.xml is older than configure.status, so regenerates gtk-doc. gtk-doc generation is a slow process at the best of times, so doing it twice isn't good.

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.
