[netCDF #SPM-769661]: netCDF Build

Hello Dave,

I don't have immediate access to the oneAPI compilers to test this, but it 
looks to me like the failures are the result of failed string comparisons.  
Specifically, when comparing different representations of NaN and Infinity.  I 
suspect these failures are safe to ignore.  I will look to see if there's a way 
we can obviate this sort of compiler-specific comparison/failure in our 
testing.  Thank you!

-Ward
