Since a few kernel releases, having 'bc' installed is mandatory to
build the kernel. See commit
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=70730bca1331fc50c3caacaea00439de1325bd6e
of the kernel.
Since this tool is generally available by default in distributions,
and we're unlikely to see version-specific problems with it, we
just check for it to be installed in
support/dependencies/dependencies.sh.

This reverts commit d66cd067f3.
SSL certificates are no always installed in /etc/ssl/certs. For example, on
CentOS 5.6 the default OpenSSL certificates directory is /etc/pki/tls/certs,
and wget can download using https without any problem.
Moreover, the existence of /etc/ssl/certs does not guarantee the presence of a
CA certificates bundle even on Debian. On my current Debian testing
installation the openssl package itself creates an empty /etc/ssl/certs
directory.

Some packages are hosted on https:// servers, and wget only works on
these if the SSL certificates are installed. For example, downloading
the kernel sources from kernel.org requires those SSL certificates to
be installed.

The host-autoconf build process requires a full Perl installation, or
at least a Perl installation that has the Data::Dumper module
installed. On a basic Debian system, only 'perl-base' is installed,
but Data::Dumper is in the 'perl' package.

The current dependencies code abort as soon as one program is
missing. It is quite annoying when multiple programs are
missing. Instead, bail out if needed after testing all programs.

awk, bison, flex, makeinfo, gettext should be built as dependencies of
packages when needed. In practice, even the toolchain build doesn't
need any of these, and only a few packages do require them.
It is not needed to list gzip and bzip2 since they are already checked
through ${DL_TOOLS}: whenever a package needs gzip or bzip2 for its
extraction, the dependency is added.

Many users trying to use external toolchains on x86-64 machines get a
very confusing message:
"Can't execute cross-compiler"
They get this message because they forgot to install the 32 bits
compatibility libraries that are needed to run binaries compiled for
x86 on x86-64 machines.
Since this is the case for both external toolchains and certain
binary-only tools like SAM-BA, we add a new Kconfig option
BR2_HOSTARCH_NEEDS_IA32_LIBS, that packages must select if they need
the 32 bits compatibility libraries. When this option is enabled,
dependencies.sh checks that the 32 bits dynamic library loader is
present on the system, and if not, it stops and shows an error.
The path and name of the 32 bits dynamic loader is hardcoded because
it is very unlikely to change, as it would break the ABI for all
binaries.
Also, it is worth noting that the check will be done even if we're
running on a 32 bits machine. This is harmless, as 32 bits machines
necessarily have the 32 bits dynamic loader installed, so the error
will never show up in this case.

Add an option in the menuconfig to specify a root password.
If set to empty, no root password is created; otherwise, the password is
encrypted using MD5 (MD5 is not the default for crypt(3), DES-56 is, but
MD5 is widely available, not-so-strong, but not-so-weak either).
Add a check for 'mkpasswd' as a new dependency.

Some toolchains, like the one built with buildroot itself, use hardlinks (for
example to link between the c++ and g++ binary). Unpacking such a toolchain
with the --strip-components options does not work correctly if the system tar
is too old (<1.17). Even recent releases of RedHat/CentOS still ship with
tar 1.15.
This patch checks for a suitable tar version (tar 1.17+) on the host system,
and adds host-tar to the host dependencies if none can be found.
host-tar is download and extracted as cpio.gz instead of tar.gz, to prevent
chicken-egg problem.

Sometimes, buildroot needs a certain host tool to do its job, e.g. tar. In
many cases, we expect this tool to be present on the host system, but this is
not always the case. Or maybe, the version on the host system is not
suitable, and we need a more recent one.
In some of these cases, instead of bailing out, buildroot could build the
package first (but only if the existing system package is not suitable).
To aid in detecting if a host package is suitable or not, this patch adds a
function suitable-host-package. When called with parameter foo, it will
execute check-host-foo.sh. This script should return either the path to the
suitable host package, or the empty string if no suitable package can be found.
The rules to determine whether something is suitable or not is left to
check-host-foo.sh and depends on foo.
An example usage of suitable-host-package is:
DEPENDENCIES_HOST_PREREQ += $(if $(call suitable-host-package,foo),,host-foo)
To avoid cluttering the existing dependencies.mk file, it includes any
check-host-foo.mk file. These files can be used to hold appropriate
dependency-related actions for foo.
