[COMMITTED] ada: Disable PIE mode during the build of the Ada front-end

[Marc Poulhiès]

From: Eric Botcazou <ebotcazou@adacore.com>

This also removes some obsolete stuff.

gcc/ada/

	* gcc-interface/Make-lang.in (ADA_CFLAGS): Move up.
	(ALL_ADAFLAGS): Add $(NO_PIE_CFLAGS).
	(ada/mdll.o): Remove.
	(ada/mdll-fil.o): Likewise.
	(ada/mdll-utl.o): Likewise.

Tested on x86_64-pc-linux-gnu, committed on master.
