The user_build_options.gfortran.serial build needs to have the -E option added to CPPFLAGS. This option enables:
-E Stop after the preprocessing stage; do not run the compiler proper. The output is in the form of preprocessed source code, which is sent to the standard output.
Otherwise, no stdout is generated, and therefore empty f90 files are created which causes strange compile issues.
