[yocto] i think the list of "required software" needs to be clarified

[Rudolf Streif]

In a sense yes. From how I understand it, anything that is listed as a
required utility in SANITY_REQUIRED_UTILITIES does not even have to be
listed in ASSUME_PROVIDED. The required native utilites should fail the
sanity test right away if they are not there.

For any dependency listed in ASSUME_PROVIDED BitBake will not attempt to
build it. But for instance, even if you do not list "tar-native" in
ASSUME_PROVIDED there is no way for BitBake to build tar since the recipe's
SRC_URI points to a tarball. Catch22.

However, I would expect that all the build essentials (awk make wget tar
bzip2 gzip python unzip perl patch diffutils diffstat git cpp gcc gcc-c++
eglibc-devel texinfo chrpath ccache) are listed in
SANITY_REQUIRED_UTILITIES.

A reason I could see to list all of the required native utilities in
ASSUME_PROVIDED could be the dependency graphs. It does not really add any
value to show the native stuff in the graphs.
