Generate ISO C for b_gnatb.c

[Matt Kraai]

Howdy,

I have committed the following patch.  It makes bindgen.adb
generate ISO C for b_gnatb.c.  It was bootstrapped on
powerpc-unknown-linux-gnu.

	* bindgen.adb (Gen_Adafinal_C, Gen_Adainit_C, Gen_Elab_Defs_C)
	(Gen_Main_C, Gen_Output_File_C): Generate ISO C.
