df0c125994 toolchain-external: allow downloading a custom toolchain
This patch adds the possibility to download a custom external
toolchain, in addition to the existing support of preinstalled custom
external toolchains.

With the modified configuration, the user is presented with the
following options:
- Toolchain type: Buildroot toolchain | External toolchain | Ct-ng toolchain

In case of External toolchain:
- Toolchain: the CodeSourcery toolchains | Custom toolchain
- Toolchain origin: Toolchain to be downloaded and installed | Pre-installed toolchain

In case of Toolchain to be downloaded, the user is presented with:
- Toolchain URL
In case of Pre-installed toolchain, the users sees:
- Toolchain Path

For CodeSourcery toolchains, the toolchain URL field is not used (the
URLs are directly coded in ext-tool.mk).

d8e1ecb855 ext-tool.mk: fix SUPPORT_LIB_DIR calculation for toolchains without libstdc++
SUPPORT_LIB_DIR would get resolved to the main buildroot directory for
external toolchains without C++ support, as:

 - gcc -print-file-name=<nonexisting-file> returns <nonexisting-file>
 - readlink -f <nonexisting-file> returns $PWD/<nonexisting-file>

So fix it by ensuring output of gcc -print-file-name actually exists
before using it.

e1f0804cc1 external-toolchain: add support for recent Linaro toolchains
Starting from 2012.03, the Linaro toolchains have separated the GCC
support libraries (libstdc++, libgcc_s) from the sysroot itself. So we
no longer have the case where all libraries are inside the sysroot, as
we had for all the previously supported toolchains.

Therefore, we add some logic to detect if such a separate directory is
used for GCC support libraries, and if it's the case, we make sure
that we take into account this directory when creating our own
sysroot, and when copying libraries to the target filesystem.

0a4856ce27 DOWNLOAD: change $1=DIRECTORY_URL, $2=FILE_NAME to $1=FULL_FILE_URL, $2=FILE_NAME
This modifies the definition of DOWNLOAD to receive two arguments:
the first one is the full URL of the file to download, whereas the second
(and optional) is the name the file will have once downloaded.

Same thing with the SOURCE_CHECK_WGET and SCP functions.

All calls to these functions have been changed to the shortest form of
the new API, except for toolchains acquisition. Since there is quite a
number of different toolchains this call to DOWNLOAD is better set to the
generic one.

c56b58b4b7 debug: provide an option to copy the gdbserver to the target
When an external toolchain is used, it is very likely that it contains
a pre-built version of a gdbserver that has the same version as the
cross-gdb included in the external toolchain. So, we now provide an
option that allows to copy this pre-built gdbserver to the target.

As the location of the gdbserver in the external toolchain is not
standardized, we only support the CodeSourcery and Crosstool-NG
layouts for the moment. Other locations can be added later.

e6e60becb0 external-toolchain: add support for Linaro 2012.01
Linaro has just released a new pre-built toolchain, available as a
tarball, which is a pure toolchain (only the C library is
included). This makes this new Linaro 2012.01 toolchain usable in
Buildroot, so let's integrate the support for it.

In addition to simply adding the new external toolchain at the usual
locations, this patch allows need to adapt a few things to support
Linaro toolchains. Most toolchains store their libraries in the "lib/"
or "usr/lib" directories relative to the toolchain. Buildroot
toolchains on the other hand, store the libraries in the
"usr/<target-name>/lib" directory. And the Linaro toolchain has
choosen to use the "lib/<target-name>" directory. Therefore, this
patch adjust:

 * The logic to search a particular library when that library needs to
   be copied to the target directory

 * The logic to deduce the sysroot directory from the libc.a file
   location in the toolchain: removing "(usr/?)lib(64?)" is no longer
   sufficient, we need to take into account the "lib/<target-name>/"
   case.

Since the Linaro toolchain generates code for Cortex-A processors
only, the selection of this toolchain is limited to Cortex-A8 and
Cortex-A9.

0729b544b3 Improve external toolchain logic to support IA32 Sourcery CodeBench toolchain
The IA32 Sourcery CodeBench toolchain has a relatively special
structure, with the following multilib variants:

 * Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative
   to the main sysroot, with the libraries in the lib64/ directory.

 * Intel Atom 32 bits, the multilib variant is in atom/ relative to
   the main sysroot, with the libraries in the lib/ directory.

 * Intel Core 2 64 bits, the multilib variant is in core2/ relative to
   the main sysroot, with the libraries in lib64/ directory.

So the first two variants are in the same sysroot, only the name of
the directory for the libraries is different.

Therefore, we introduce a new ARCH_LIB_DIR variable, which contains
either 'lib' or 'lib64'. This variable is defined according to the
location of the libc.a file for the selected multilib variant, and is
then used when copying the libraries to the target and to the staging
directory.

In addition to this, we no longer use the -print-multi-directory to
get the ARCH_SUBDIR, since in the case of the 64 bits variants of this
toolchain, it returns just '64' and not a real path. Instead, we
simply compute the difference between the arch-specific sysroot and
the main sysroot.

We also take that opportunity to expand the documentation on the
meaning of the different variables.

9eaad202f1 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.

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.
