debug/ltrace: Add support for ltrace-0.5.3

From this version of ltrace the maintainer has removed support for
GNU Autotools, so the patch sets needed to be reworked.

Included is the latest Debian patch, by the Debian ltrace maintainer
Juan Cespedes <cespedes@debian.org>, the OpenEmbedded patches for cross
compiling, by Khem Raj <raj.khem@gmail.com> and a further set of patches
by Joachim Nilsson <jocke@vmlinux.org> for crosstool-NG.

samples: refine the listing of all samples for canadian samples

For canadian samples, display the sample as:
target-tuple (host: host-tuple)

samples: add an action to print details for all samples

samples: fix displaying samples

samples: add a new samples for the TI DaVinci processors.

I was able to successfully build and run v2.6.27-davinci1 kernel
(Kevin Hilman's branch) with busybox based initramfs on it. I don't
believe that any later kernel would represent any challenge (it just
happens that I'm currently working with this version). What a thrill
:).

crosstool-NG/toolchain config is attached. It may be useful to someone
using crosstool-NG ...

scripts/functions: make aria2 less verbose when downloading

Merge.

misc: do not use "tar cf - |tar xf -"

Using this: tar cf - -C "/some/place" |tar xf - -C "/some/other/place"
to copy a directory to another place does not properly fail (when it does).

Using this instead: cp -av "/some/place" "/some/other/place"
makes it easy to see why and how it failed.

Impacted:
libc/uClibc
debug/ltrace
tools/sstrip
scripts/populate

Merge.

cc/gcc: update ptachsets for gcc-4.4.{0,1,2}

As reported by Joachim Nilsson <jocke@vmlinux.org>
in: http://sourceware.org/ml/crossgcc/2010-01/msg00005.html

It seems I need to add the 4.3.4/290-index_macro.patch to the GCC 4.4.x
series as well. I immediately trigger the following libstdc++ bug for
4.4.2 with a uClibc .config which has UCLIBC_SUSV3_LEGACY_MACROS set[1].

scripts/functions: fix downloading with aria2

In case the remote file does not exist (and probably for some
other reasons as well), aria2 nonetheless creates an empty file
(or not empty for some other reasons).

The solution is to delete the file whenever aria2 fails.

scripts/functions: fix using Aria2

Latest aria2 no longer recognise the --retry-wait option.

debug/strace: fix strace 4.5.19 to properly build with latest Linux kernels

Here's a couple of patches to get strace 4.5.19 to configure and build
properly with the latest kernel headers. Not pretty, but hopefully
enough while we wait for 4.5.20 to be released.

With the current strace-4.5.19 patches I failed to get the configure
script running even on my host environment. Also, when cross building
the configure script needs to look for the proper system headers to be
able to properly set HAVE_LINUX_NETLINK_H. Otherwise you get:

[EXTRA] Building strace
[ERROR] /home/jocke/x-tools/targets/src/strace-4.5.19/net.c:976:
error: field 'nl' has incomplete type
[ERROR] make[2]: *** [net.o] Error 1
[ERROR] make[1]: *** [all] Error 2

The fix was simple, backport a change set from the git[1] tree and run
autoreconf to update the configure script.

debug/tools: set the ncurses extension to .tar.gz

TRying to download every extension in turn takes ages, so
help the helper by telling what extension to retrieve.

scripts/functions: add aria2, a powerfull downloader

aria2 is a powerfull downloader that is capable of chunking and
parallel retrieval.

Due to li;itations in crosstool-NG retrieval facilities, it's not possible
to take fully advantage of aria2. It might happen that, in the future,
those limitations get lifted away, so we can take use features such as
parallel downloading from more than one server at the same time. For now,
it should still speed up downloads thanks to parallel downloading of chunks.

scripts/functions: simplify wget vs. curl check

config: fix generated config files when GREP_OPTIONS set --color=always

grep is used when generating some .in files (in config.gen). If GREP_OPTIONS
contains --color=always, then the generated files will contains some escape
sequences setting the color, and mconf would choke on those escape sequences.

Always set and export an empty GREP_OPTIONS to avoid that.

scripts: check for, and warn about an unset CT_PREFIX_DIR

The user shall provide a directory to install the toolchain into.
If he/she does not, this is an error, and shall be detected properly,
rather than relying on failure down the road.

scripts: correctly warn when the local tarballs directory does not exist

Warn about a missing local tarball directory, only if it was configured.
Avoid the spurious message:
Directory '${CT_LOCAL_TARBALLS_DIR}' does not exist.
Will not save downloaded tarballs to local storage.

configure: install in a sub-dir of --libdir and --docdir

In case the user specifies the LIBDIR with --libdir , or DOCDIR with
--docdir, install our support files in a sub-dir, so as not to mangle
existing (potentially system) files/dirs.

scripts: directly spit-out the date in the WiKi table, misc eye-candy

No need to go through a post-processing just for displaying the date...

scripts: fix Host/Target colums in WiKi table

Generate a better-looking WiKi table by re-arranging
the host and target columns.

scripts: fix WiKi table generation

The number of column in the top-most header was not updated to reflect the
fact that a new column was added to show the host (for canadian crosses).
