During the extensible SDK installation process the final step is to
prepare the internal copy of the build system. This can take some time,
especially if you have SDK_EXT_TYPE set to "minimal" (downloading
sstate artifacts) and SDK_INCLUDE_PKGDATA set to "1" (restoring
pkgdata for world). To make this a bit less painful, use BitBake's new
quiet mode to display status during this operation so you have some idea
of how it's progressing; instead of redirecting the output to
preparing_build_system.log we grab the last console log and append it
instead.
Part of the implementation for [YOCTO #9613].
