Yes.

Do I need therefore the Developer Suite on the linux machine?
No.

Read something about f90genm.sh , which user should compile the .fmb files under linux? How to compile the .fmb file (which parameters are necessary)?
Run the executable against the fmb files. Look in the Form Builder reference guide for instructions.
