[PATCH 0 of 1] Support for ltrace-0.5.3 in crosstool-NG

[PATCH 0 of 1] Support for ltrace-0.5.3 in crosstool-NG

[Joachim Nilsson]

Hi Yann!

Here is my attempt at adding support for ltrace-0.5.3 to crosstool-NG.

Since 0.5.3 and later need a bit of special treatment I've added this
${CT_LTRACE_0_5_3_or_later} to the .config file.  Similar to what is
done for GCC.  Hope this is OK?

The patches have been updated and complemented with new ones as well.
Most notably the Debian patch and the cross-compile patches from the
OpenEmbedded folks.  Despite this I did however not get it working,
so I added a couple of extra patches to add support for target ARCH
and compilation fixes for events.c, on Arm.

Yes, I've only tested on Arm, hence the 0.5.3 is marked EXPERIMENTAL.
Hopefully there are others that can help out testing on other archs.

Regards
 /Joachim

[PATCH 1 of 1] debug/ltrace: Add support for ltrace-0.5.3

# HG changeset patch
# User Joachim Nilsson <jocke@vmlinux.org>
# Date 1262533618 -3600
# Node ID d284ddf7e1b40cedcea0d6e0cf54b59a1a1b737a

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.
