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 <r...@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.
