building with oneAPI fails

[manodeep]

With the latest oneAPI compiler (and leaving netcdf and openmpi as is), I get the following error when I try to compile the oasis3-mct package. Same error also occurs upstream, but is not caught and the compile continues past this error. This happens because there is an extra -loopopt=0/1 option that is not correctly parsed and interpreted as a linking flag. The linker then looks for a non-existent file and borks.

Intel says this is an autoconf issue (see release notes for 2025 oneAPI) and can be fixed by using autoconf>=2.70 and using autoupdate. I have tried that but that does not fix the issue.
