debian/patches: Add 2004_enforce-lpthread.patch. On Debian, enforce -lpthread when building nxcomp. This is a nasty work around for a missing symbols issue that needs to get addressed otherwise in later release.

+Description: Enforce -lpthread when linking nxcomp.
+Author: Mike Gabriel <mike.gabriel@das-netzwerkteam.de>
+Abstract:
+ This is a workaround for a nasty libtool bug!!!
+ .
+ We actually compile libXcomp with pthread support, but libtool uses g++
+ ... -nostdlib ... -pthread on Linux. -nostdlib causes -pthread to be
+ ignored.
+ .
+ According to GCC upstream, this is not a bug:
+ https://gcc.gnu.org/bugzilla/show_bug.cgi?id=25460
+ .
+ GCC upstream insists that libtool needs to handle -pthread in a special
+ way when using -nostdlib.
+ .
+ A patch has been submitted to the libtool project:
+ http://lists.gnu.org/archive/html/libtool-patches/2013-11/msg00015.html
+ but never applied to the code base. Boo.
+ .
+ We will work around this bug by hard-coding the linking with pthread
+ support in libXcomp for now.
