u-boot: add CROSS_COMPILE/ARCH when building host tools

Even when building the host tools, for some reason U-Boot tries to
execute the cross-compiler, so tell it which cross-compiler to use in
order to avoid failure such as:

/usr/bin/make -j12 -C /home/test/outputs/test-253-mini2440_defconfig/build/u-boot-custom tools

board: add support for Mini 2440

Paul Jones documented at
http://pauljones.id.au/blog/2010/07/using-buildroot-on-a-mini2440/ how
to use Buildroot to generate a system for the FriendlyARM Mini2440
platform. This patch integrates Paul's work into Buildroot.

Unfortunately, the kernel being 2.6.32, we can't easily use a minimal
defconfig here. The mini2440 support has been merged into more recent
kernels, but I don't have the hardware to test.

It was supposed to be the support for AT91SAM9260 using a parallel flash
(instead of the usual dataflash). But the provided U-Boot configuration
at91sam9260pf.h was not used anywhere, and it was unsufficient to add
correct support in U-Boot (some changes in U-Boot Makefile would also be
needed). Additionnally, this configuration has not been merged into U-Boot
upstream since 2007 (when it was added to Buildroot).

Therefore, let's get rid of this configuration. If some users are
interested, we can re-introduce it properly with their help.

complete copies of new target skeletons (making them hard to

adds/removes/tweaks the existing target skeleton.

Moreover, most of the tweaks in this target skeleton were for specific
packages, but the policy now is that board defconfig should just build
a basic root filesystem with Busybox, and let the user select

require the build of a JFFS2 filesystem, very uncommon on PC systems,

It would make more sense to have a qemu_i388_defconfig (building a
kernel with just the device drivers for Qemu) and possibly a
pc_i386_defconfig (building a kernel with many device drivers, and a

package: pass TARGET_MAKE_ENV at install/clean/uninstall steps

TARGET_MAKE_ENV contains the PATH to the host tools built in
$(HOST_DIR), and not having this directory in the PATH while
installing packages may cause troubles.

The specific example that trigerred the problem is the following
one. libglib2 ./configure tries to find a awk version, either gawk or
mawk. On my limited testing system, only mawk is available, so
normally, libglib2 detects mawk and uses it, and it works perfectly.

However, when host-gawk has been compiled before libglib2 (which
happens for example if you have used the Crosstool-NG backend), gawk
is well detected in $(HOST_DIR)/usr/bin at ./configure time
($(HOST_DIR)/usr/bin is in the PATH at ./configure time, thanks to
TARGET_MAKE_ENV). But at install time, when libglib2 uses gawk, it
doesn't find it anymore because it is not in the PATH.

This also makes things coherent with host installation, in which
$(HOST_MAKE_ENV) was already used.

By default, Crosstool-NG hides all the details of the toolchain build
process. However, this is inconsistent with the typical Buildroot
build, and the rotating progress thing makes log file resulting from
redirecting the Buildroot output a bit unusable. Therefore, switch the
Crosstool-NG configuration to a more verbose default.

When an external toolchain is used, the user is responsible for

toolchain: rework thread options

The selection of linuxthreads, linuxthreads old or NPTL doesn't make a
lot of sense for external toolchains. So, instead, we :

 * Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be
   selected by toolchain specific options when thread support is
   available. Package needing to test thread support should use this
   option.

 * Move the none/linuxthreads/linuxthreads old/NPTL selection to
   Buildroot internal toolchain configuration.

 * Add an option in external toolchain to tell if thread support is
   available or not in the external toolchain. We assume that glibc
   without threads is not possible, as Ulrich Drepper said in
   http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html

ffmpeg, dmalloc and openvpn are fixed to use the new
BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix
is no longer used, as the configure script doesn't even understand
this option.

toolchain: rework C++ options

Instead of having BR2_GCC_CROSS_CXX and BR2_INSTALL_LIBSTDCPP, with
BR2_GCC_CROSS_CXX not being visible (and therefore being useless),
let's just keep BR2_INSTALL_LIBSTDCPP to enable C++ in the toolchain
and install C++ libraries on the target.

We also take that opportunity to make BR2_INSTALL_LIBSTDCPP an hidden
option, which is selected by an option in Buildroot toolchain support
or an option in External toolchain support, just as we did for other
toolchain features.

Some work definitely remains to be done :

 - The name BR2_INSTALL_LIBSTDCPP is ugly, but we keep it for the
   moment in order to avoid changing all packages.

 - We should clarify the other language-related options (Fortran,
   Java, Objective-C, etc.).

toolchain: add support for external toolchain profiles and download

Instead of letting the user define all the details of his external

toolchains (CodeSourcery ones only at the moment, can easily be
extended with other toolchains).

Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,
or (as before) to tell Buildroot where the toolchain is installed on
the system.

We of course provide a "custom profile", through which the user can
configure Buildroot to use a custom external toolchain for which no
profile is available.

toolchain: Improve C library option selection

Turn BR2_LARGEFILE, BR2_INET_IPV6, BR2_INET_RPC, BR2_USE_WCHAR,
BR2_ENABLE_LOCALE and BR2_PROGRAM_INVOCATION into hidden options.

Then, for Buildroot toolchains, external toolchains and Crosstool-NG
toolchains, provide visible options that selects the hidden options.

This allows :

 * To show a different label and help text in the case of Buildroot
   toolchain (do you want to enable feature X ?) and in the case of
   external toolchain (is feature X available in your toolchain ?)

 * To not show any option when a glibc external toolchain is selected
   (since glibc is assumed to support all of largefile, IPv6, RPC,
   WCHAR, locale and program invocation) and have them all selected in
   that case.

There is some amount of duplication between Buildroot toolchain config
options and Crosstool-NG toolchain config options, because kconfig
doesn't allow to source the same Config.in file twice (even if under
mutually exclusive conditions). This duplication is more readable that
the hack that consists in splitting files in multiple pieces.

However, this commit changes the name of the options visible in the
configuration interface, so existing .config files will have to be
updated accordingly.
