#1184: Update ubuntu.cfg
-------------------------+--------------------------------------------------
 Reporter:  eschnett     |       Owner:  eschnett
     Type:  enhancement  |      Status:  new     
 Priority:  minor        |   Milestone:          
Component:  SimFactory   |     Version:          
 Keywords:               |  
-------------------------+--------------------------------------------------
 I suggest to update ubuntu.cfg:

 - remove some outdated comments
 - consolidate Fortran line length options
 - add -ffast-math
 - correct Fortran OpenMP flag
 - move -rdynamic to LDFLAGS
 - add -Wall
