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.
