[Mvapich] Error Encountered in MVAPICH 3.0 Configuration with oneAPI 2024 in Spack 0.21

[Paul H. Hargrove]

ZQ,

I believe the configure probe you are referring to has attempted to compile
a short F90 program and then run it.
The result you report is consistent with the run having failed.

You should examine the contents of the config.log file, searching for the
text "checking whether the Fortran 90 compiler" and then looking after that
for the run failure that led to declaring ifx a cross compiler.

If I had to guess without seeing config.log, then I would guess that the
compiled executable failed to run due to not locating a shared library.
This could occur, for instance, if the `-Wl,-rpath...` argument is
incorrect or incomplete.  In particular, it doesn't seem to "match" the
full path to ifx.
