What's the best way to make a build with just a few flags different for static analysis?

[MichaelBonnet]

I'm trying to use the ikos static analyzer to analyze my cFS project. Unfortunately, some of the cFS compilation flags aren't compatible, as you can see in my issue in that repo.

Essentially, I need to cut out:

-Wno-format-truncation
-Wno-stringop-truncation

and add in:

-Wno-newline-eof
-Wno-non-literal-null-conversion

just for when I want to use ikos-scan to intercept the build process and perform analysis.

My question is: what's the best cFS-y way to make a second, parallel build process with just a few compilation flags different?
