Allow building a vaxfloat runtime by setting a target system.ads boolean, vice having a build directory gnat.adc configuration pragma and the attendant and repeated full runtime recompilation with gnatmake. Tested on x86_64-pc-linux-gnu, committed on trunk 2013-04-25 Doug Rupp <rupp@adacore.com> * targparm.adb (VXF{_Str}): New tag for vaxfloat. (Get_Target_Parameters): Handle VXF tag. * targparm.ads (VAX_Float_On_Target): New boolean. * system-vms-ia64.ads (VAX_Float): New boolean. * frontend.adb (Frontend): Handle VAX float boolean.
