cad/feappv: Fix CFLAGS support
This problem could also be fixed by changing the sed pattern, but the
patch provided to the PR was tested. The maintainer has not responded
to the last entries in the PR for over 15 days, so I'm timing it out.

Add feappv 2.0, finite Element Analysis Program "personal version".
This is a FEA program used in a classic FEM book. A complete (commercial)
version is available here:
The "personal version" is very limited, but it keeps the same format as
the complete (commercial) version and cad/netgen can produce files for it.
