[Buildroot] [git commit] package: add the duma memory debugging library

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=bda69bf4e4b642ab199ffa13c7356709885f129d
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Add the duma memory debugging library. This is based on an earlier
patch by Baruch Siach, with minor changes to build for latest
buildroot sources.

[Thomas P: misc cleanups, drop non-C++ support as it wasn't compiling,
added thread dependency.]
