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.
