When compiler switch -gnatC is used, invoking gnatmake with switch -s
was always recompiling. This patch ensures that switch -gnatC does not
trigger recompilation, same for -gnateS switch.

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

2010-06-23  Vincent Celier  <celier@adacore.com>

	* switch-m.adb (Normalize_Compiler_Switches): Take into account -gnatC
	and -gnateS.
