Soft treating of multiple architectures in VHDL 

In VHDL it is allowed to have multiple architectures
per one entity. The proper architecture should be then
chosen in a configuration block. Now, if many architectures
will be found, then there will be a warning message printed.
FIXME notes are added in order not to forget about changes to
be done
