+Build argp object files with -fPIC.
+
+The argp bundled dependency is linked to the libwvutils.so shared library.
+MIPS will refuce to link a non-PIC library with a shared one.
+
+We fix this problem by building the argp source files using -fPIC since
+the libargp static library will only be used to link to libwvutils.so
+as instructed by the following rule in the root Makefile:
+
+ifeq ($(USE_WVSTREAMS_ARGP),1)
+  utils/wvargs.o-CPPFLAGS += -Iargp
+  libwvutils.so-LIBS += -Largp -largp
