Arnout Vandecappelle (Essensium/Mind) 29d5b79b73 utils/genrandconfig: check core-dependencies
When generating a random configuration, also check the host
dependencies for that configuration and error out if it fails.

This is mainly intended for the autobuilders, so they don't try to
build a configuration for which the necessary host packages are not
installed.

Instead of erroring out, we could also generate a different random
config. However:

- When called for the autobuilders, the autobuild-run script will
  anyway just attempt another build. The only difference is that a
  warning will be printed in this autobuild log now. This warning
  is in fact quite useful to hint that the autobuilder could benefit
  from intalling this additional host package.

- When called manually, the user may in fact want to install the
  missing host package and continue with the saved random config.

Fixes:

This directory contains various useful scripts and tools for working
with Buildroot. You need not add this directory in your PATH to use
any of those tools, but you may do so if you want.

brmake
    a script that can be run instead of make, that prepends the date in
    front of each line, redirects all of the build output to a file
    ("'br.log' in the current directory), and just outputs the Buildroot
    messages (those lines starting with >>>) on stdout.
    Do not run this script for interactive configuration (e.g. menuconfig)
    or on an unconfigured directory. The output is redirected so you will see
    nothing.

check-package
    a script that checks the coding style of a package's Config.in and
    .mk files, and also tests them for various types of typoes.

genrandconfig
    a script that generates a random configuration, used by the autobuilders
    (http://autobuild.buildroot.org). It selects a random toolchain from
    support/config-fragments/autobuild and randomly selects packages to build.

get-developpers
    a script to return the list of people interested in a specific part
    of Buildroot, so they can be Cc:ed on a mail. Accepts a patch as
    input, a package name or and architecture name.

scancpan
    a script to create a Buildroot package by scanning a CPAN module
    description.

scanpypi
    a script to create a Buildroot package by scanning a PyPI package
    description.

size-stats-compare
    a script to compare the rootfs size between two different Buildroot
    configurations. This can be used to identify the size impact of
    a specific option, of a set of specific options, or of an update
    to a newer Buildroot version...

test-pkg
    a script that tests a specific package against a set of various
    toolchains, with the goal to detect toolchain-related dependencies
    (wchar, threads...)
