From c08ee778588c9e0752e242c201000f1f11a0b742 Mon Sep 17 00:00:00 2001

Subject:     Rearranged where the substitution occurs.

    libtool does not pass the correct argument linking (-WL,-WL,,) for the
    NAG Fortran compiler on Linux (other OSs have not been tested).
    Therefore, detect if we are using the NAG Fortran compiler, and replace
    the wl="-Wl," for Fortran to wl="-Wl,-WL,," in the libtool file. (HDFFV-10037)

 ## HDF5 configure code created by autotools with gcc 4.9.2 is adding problematic
 ## linker flags:  -l with no library name; -l <libname>, specifically gfortran or m.
 ## This sed script corrects "-l <libname>" first and then "-l " with no library name.
