38b81eb172 support: properly check bash is available
The current check is broken, as it only checks if the user's login
shell is bash, not what the system shell is.

Mimick the sequence found in the top-level Makefile to search for
bash, except for the fallback case, where we explicitly check that
'sh' is bash, by checking if it sets $BASH, so we know the fallback
case, in the top-level Makefile, to use 'sh' will indeed use bash.

Remove superfluous semi-colons ';' at the end of lines, they are
not needed in a shell script (this is not C!)

0721c71330 infra: Change BR2_HOST_NEEDS_JAVA name
Change BR2_HOST_NEEDS_JAVA to BR2_NEEDS_HOST_JAVA as it makes more
sense.
The host doesn't need Java but Buildroot needs the host to have
Java in order to build the package that select this option.

aac3d2b402 infra: Introduce BR2_HOST_NEEDS_JAVA
XBMC needs Java on the host in order to build, because it uses a
code-generator which is built in two phases: In the first phase SWIG is used
to parse C++ header files that define the API.  SWIG outputs an XML file
that contains a complete description of the structure of the API.  In the
second phase, the XML file is ingested by a Groovy (Java) program that then
creates C++ code that forms the bridge to the scripting language (Python).

The second phase is why we need java on the host.

You can learn more at the XBMC's wiki:
http://wiki.xbmc.org/index.php?title=Codegeneration#How_it_works

In order to check that, this patch introduce this mechanism in
dependencies.sh, and it also defines the variable in Config.in

4113b3c3bd infra: replace BUILDROOT_CONFIG with BR2_CONFIG
To make the naming consistent (all user-visible options should be
prefixed with BR2_).

An entry is added to Makefile.legacy to warn users who have set
BUILDROOT_CONFIG but not BR2_CONFIG.

Still export BUILDROOT_CONFIG but pointing to some phony value, to
make sure that scripts that still use it fail in a predictable way.

2e8dd9563d dependencies.sh: stop stray a.out being created for ia32 compiler test
If the grub package is selected it also selects
BR2_HOSTARCH_NEEDS_IA32_COMPILER.  This triggers a test in dependencies.sh
to verify the host compiler can build 32 bit executables.  Currently this
test does not set any output for the compiler which causes a stray a.out
to be create outside the output directory.  This patch sets the compiler
output to /dev/null so no a.out is created but the test is still performed.

e8160146e6 dependencies.sh: stop mixing echo and printf (use echo)
'printf' was introduced because it is more portable than 'echo -e'. But
when the escape sequences are just newlines we can just as well use
plain 'echo' (and remove the newline escape sequences).

This looks cleaner than having some lines with echo and some with
printf.

221ef3a3ee Prefer 'printf' over 'echo -e' (for portability)
support/dependencies/dependencies.sh uses #!/bin/sh shebang. It is not
guaranteed that /bin/sh provides an 'echo' implementation that
understands the '-e' flag (interpret backslash escape chars). For
example, dash doesn't.

'printf' is more portable (it must interpret backslash escape chars,
according to POSIX), so use that.

NOTE: Before the previous commit, the dependencies.sh script used
/bin/echo instead of the shell built-in. That's probably why this hasn't
come up before.

0e4bc50210 core: add BR2_HOSTARCH_NEEDS_IA32_COMPILER option
Some bootloaders (such as Grub) need to be built for x86 (i.e IA32)
even if the target architecture is x86-64. However, when the target
architecture is x86-64, the cross-compiler generated by Buildroot is
not able to generate 32 bits code.

To solve this, we will rely on the host compiler being a x86 + x86-64
compiler. Therefore, this commit introduces the
BR2_HOSTARCH_NEEDS_IA32_COMPILER option, which tells the dependency
checking logic to verify that the host compiler is indeed capable of
building x86 32 bits code.

59e0692095 host-mkpasswd: new package
Since the addition of root password setting support in buildroot, there have
been a few bug reports in this area ([1], [2]). In these cases, the system
mkpasswd did either not work, or did not provide the options we expect, like
-m <method>.

This patch adds a mkpasswd host package, based on the sources from whois. When
a non-empty root password is set, this package is used as a dependency.

7cbebbc48c Add 'bc' in the mandatory dependencies
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.

1e7f40ebb5 Revert "dependencies: check that SSL certificates are installed"
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.

d8f9237553 dependencies: remove a few useless mandatory dependencies
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.

70d6037e8a Infrastructure to warn the user about missing 32 bits libraries
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.

a45871bfc6 target: add option to set the root password
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.
