Compile by default MySQL clients with libmysqldclient.a (not .so)

This makes them suitable for tar archices right away and also are easier to copy
Don't disable federated storage engine by default.
Don't allow one to disable the Maria storage engine if it's used for temp tables

BUILD/SETUP.sh:
  Compile by default MySQL clients with libmysqldclient.a (not .so)
  This makes them suitable for tar archices right away and also are easier to copy
scripts/make_binary_distribution.sh:
  Abort it clients are compiled with the shared libmysqlclient.so library
sql/mysqld.cc:
  Don't call kill_mysql() if signal handler is not setup (causes a core dump).
  This is only relevant when starting with --gdb.
sql/sql_plugin.cc:
  Don't disable federated storage engine by default.
  Don't allow one to disable the Maria storage engine if it's used for temp tables
