 define Package/libpthread-stubs/description
+This library provides weak aliases for pthread functions not provided in libc
+or otherwise available by default.  Libraries like libxcb rely on pthread
+stubs to use pthreads optionally, becoming thread-safe when linked to
+libpthread, while avoiding any performance hit when running single-threaded.
+libpthread-stubs supports this behavior even on platforms which do not supply
+all the necessary pthread stubs.  On platforms which already supply all the
+necessary pthread stubs, this package ships only the pkg-config file
+pthread-stubs.pc, to allow libraries to unconditionally express a dependency
+on pthread-stubs and still obtain correct behavior.
