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)

Removed FCFLAGS when building the examples since they should already be included the h5fc wrapper. NAG complains about doubly declared options.
