+pkg-config: needs pthread as private library
+
+libtirpc needs pthreads. This is automatically pulled in when linking
+with the shared library, thanks to the DT_NEEDED ELF tags.
+
+But for a static library, there is no such mechanism to identify
+required libraries.
+
+Thus, add -pthread to the private libraries in the pkg-config file.
