[Ipopt] example.for asks for MA_47

[Stefan Vigerske]

Hi,

I don't think there is still support for the Fortran version of Ipopt.
That said, it seems to use MA47 if option QSYMSOLV is set to 0. This is 
the default only if MA27 and MA57 are not available.
So maybe check whether configure correctly recognized the HSL library. 
It could also be that the 11 years old configure script that comes with 
Ipopt for Fortran does not work correctly anymore on current systems.
