prj-makr.adb (Process_Directory): Put file name in canonical case before matching against the patterns.

	* prj-makr.adb (Process_Directory): Put file name in canonical case
	before matching against the patterns.
	If gnatname has been invoked as <prefix>-gnatname
	then invoke the compiler as <prefix>-gcc, not just "gcc".
