PAPI does not detect ifort correctly

[Roland Haas]

PAPI's makefile attempts to set options for the fortran compiler and checks for the intel compiler suite by comparing F77 to the string ifort. This breaks since for Cactus F77 is not ifort but something along the lines of /long/path/to/ifort . The attached patch replicates the methods that the Makefile already uses to identify the C compiler to identify the F77 compiler.

Keyword: PAPI

Now that the Wu release is done, it is time to review and include or reject this.
