Are you still passing "-c" in FCFLAGS as you indicated in your first 2
posts? If so, this is why your fortran compiler is not creating an
executable. As you can see by the line below:

configure:2508: ifort -c -O2 -convert big_endian -free -assume
                                 ^
                          This is why no executable is created.

Why are you using -c? Don't do this.
