Fortran has to be enabled by seperate flags. I was using the same flags as used by teh C interface which built fortran bindings even when the user has disabled them

+# There are 2 layers to the MPI f77 layer. The only extra thing
+# that determine f77 bindings is that fortran can be disabled by
+# user. In such cases, we need to not build the target at all.
+# One layer generates MPI_f77* bindings. The other layer
+# generates PMPI_f77* bindings. The following conditions
+# determine whether each (or both) these layers are 
+# built.
+# Superceeding clause:
+#   - fortran77 bindings should be enabled, else everything is 
+#     disabled
+# 1. MPI_f77* bindings are needed if:
+#	- Profiling is not required
+#   - Profiling is required but weak symbols are not
+#	  supported
+# 2. PMPI_* bindings are needed if profiling is required.
+# Hence we define 2 AM_CONDITIONALs which tell us whether
+# each of these layers need to be built or NOT
