Use of "-Wl," in darshan-config and darshan-runtime.pc

Given "-Wl," is for gcc to pass an option to the linker, I wonder if it is necessary to use them in darshan-config and darshan-runtime.pc, as it is only added to *_LD_FLAGS in darshan-config.in and Libs in darshan-runtime.pc.in. Using "-Wl," only makes sense when it appears in CFLAGS.
