Subject: [Ada] GNAT driver command line

The GNAT driver put the command line it has been invoked with in
environment variable GNAT_DRIVER_COMMAND_LINE, so that the spawned tool
may know the way the GNAT driver was invoked. No visible change of
behavior, so no test.

Tested on x86_64-pc-linux-gnu, committed on trunk

2010-09-10  Vincent Celier  <celier@adacore.com>

	* gnatcmd.adb (GNATCmd): Put the command line in environment variable
	GNAT_DRIVER_COMMAND_LINE.
