[Patches] Add configuration flag PROFILE=yes

[Erik Schnetter]

Add a new configuration flag PROFILE=yes, which enables profiling in  
a build.  This flag is equivalent to OPTIMISE=yes and DEBUG=yes.   
Additional compiler options {C,CXX,F77,F90}_PROFILE_FLAGS are also  
introduced.

The configuration stage sets the F77 flags to the F90 flags if an F90  
compiler is found.  This flag setting was done too early, namely  
before the default values for the F90 flags were set.  This flag  
setting has been moved to a later time.

The link command used undefined make variables $(OPTIMISE_C) etc.   
These variables have been removed.  Instead $(CXX_OPTIMISE_FLAGS)  
etc. are added to the link statement.  This makes the linker pick up  
the correct flags e.g. for profiling.
