gcc_target wants uclibc_target which is now first stage uclibc (not
real, from the NPTL build stage addition).
This triggers gcc-final to be rebuilt (albeit cached) and reinstalled,
thus touching all the stamps around and triggering a rebuild of
gcc_target.
Switch to $(STAMP_DIR)/gcc_libs_target_installed instead so that we only
depend on the last stage of cross gcc being installed to rebuild.

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

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.).

Once a profile has been choosen, the user is offered the choice of
either letting Buildroot download and install the external toolchain,

the system.
We of course provide a "custom profile", through which the user can

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.

to gcc. You have to actually build the C library several times (once
for each multilib variant you want to support in your toolchain), and
to pass MULTILIB_OPTIONS/MULTILIB_EXCEPTIONS values to gcc to let it
know the set of multilib variants you're interested in.
Since we'll probably never support multilib toolchains in Buildroot,
just get rid of this BR2_ENABLE_MULTILIB option.

This is a very advanced option, and it seems, according to
http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't
really interesting.
Users really interested by this can always use the
BR2_EXTRA_GCC_CONFIG_OPTIONS is they want.

Handle the internal toolchain backend mechanism the
same way we handle other backends.

Including a bunch of Makefiles with wildcard makes it impossible to add
new toolchain backends. Avoid that by namely including needed files.
The external toolchain still needs to include all the toolchain/*/*.mk
sub-makefiles, as they are needed to build a toolchain that runs on the
target. It is to be noted that the cross-toolchain is not built in this
case, as the make-targets to build the cross-toolchain are not present
in the $(BASE_TARGETS) variable, which is later used to create the
dependency rules.
Also, the comment 'Explicit ordering' has been removed, as it is mis-
leading. It is make's responsibility to create the proper ordering based
on the dependency rules it finds in the Makefiles

Rename the external toolchain directory.
When new backends are here, it will be easier to sort them out
if they are all prefixed the same way.

The helper functions used for external toolchains may also be useful
to alternate toolchain backends (currently, the external toolchain is
the sole user).

This option is already part of the gcc configure options through the
BR2_CONFIGURE_BUILD_TOOLS variable (in toolchain/Makefile.in).
Additionnally, the value that was passed in the AVR32 specific case
was incorrect: it was $(STAGING_DIR)/$(REAL_GNU_TARGET_NAME)/bin
instead of $(STAGING_DIR)/usr/$(REAL_GNU_TARGET_NAME)/bin.

The variable BR2_SYSROOT_STAGING_DESTDIR is no longer used, since now
the prefix for gcc is already set to the correct location.
The variable BR2_SYSROOT_TARGET_DESTDIR was already unused.

The cross binutils and cross gcc are actually going to be executed
from $(STAGING_DIR)/usr, so the correct prefix is $(STAGING_DIR)/usr
and not /usr.
This also fixes what is known as the "AVR32 toolchain build failure",
which was due to the fact that the prefix directory wasn't writable
(since it was /usr).

This commit solves bug #1051. The problem in this bug in that WebKit
compiles a sample C program, which uses WebKit. As WebKit is written
in C++, even though the program it built with CROSS-gcc, it must be
linked with libstdc++. However, CROSS-gcc can't find the libstdc++ has
it's hidden inside <sysroot>/<tuple>/lib.
Therefore, this commit creates a symbolic link <sysroot>/<tuple>/lib
-> <sysroot>/lib before running the CROSS-gcc installation. While this
may look like a hack, this is the solution used by both Crosstool-NG
and OpenWRT.
Moreover, with this symbolic link in place, I think bug #1741 may also
be solved. The problem in this bug is that the linker tries to link
against /lib/libc.so.0. This is due to the fact that the linker finds
a libc.so script file in the original toolchain location and not
inside the copy of the toolchain sysroot in $(STAGING_DIR). As the
script file is found outside of the current toolchain sysroot, ld
considers the script has non-sysrooted, and therefore doesn't prefix
all paths found in the script file (such as /lib/libc.so.0) with the
sysroot path, leading to the failure.
So, in details, this commit :
* Adds a BR2_ARCH_IS_64 invisible config knob that is used to know if
the arch is a 64 bits architecture or not.
* Creates the <sysroot>/<tuple>/lib -> <sysroot>/lib symbolic link,
and the <sysroot>/<tuple>/lib64 -> <sysroot>/lib64 symbolic link if
needed.
* Fixes the external toolchain sysroot detection code so that the
'sed' replacement is done *after* the readlink -f evaluation.
I have tested this by building ARM, x86 and x86_64 toolchains with
Buildroot, and then use these toolchains as external toolchains to
build a full X.org/Gtk/WebKit/Midori stack. I have also done a
complete ARM Buildroot internal toolchain build with the same full
X.org/Gtk/WebKit/Midori stack.

Just as we did to fix target-gcc, pass CXX_FOR_TARGET when building
target g++, and remove useless copies of g++ and c++.
Tested on ARM by compiling a simple C++ program using <iostream> on
the target and running it.

When doing the "make install" of target, three identical copies of gcc
are installed in $(TARGET_DIR)/usr/bin:
039adcc582c365f12ba6fc5f96098128 arm-unknown-linux-uclibcgnueabi-gcc
039adcc582c365f12ba6fc5f96098128 arm-unknown-linux-uclibcgnueabi-gcc-4.3.5
039adcc582c365f12ba6fc5f96098128 gcc
This patch removes the first two copies and keeps only the common "gcc" one.

Now that $(STAGING_DIR)/usr/bin is no longer in the PATH, we need to
pass the absolute paths to $(TARGET_CC) when building the target gcc
compiler.
This commit fixes the target gcc build problem reported on the list. I
have successfully been able to build a target gcc for ARM, use it to
compile a hello world application on the target and run this
application.
