Not clear why this never showed up on the 4.6 branch, but this now prevents a 
parallel LTO bootstrap with Ada enabled from completing on the mainline.

Parallel LTO-bootstrapped, applied on the mainline and 4.6 branch.

	* gcc-interface/Make-lang.in (gnat1): Prepend '+' to the command.
	(gnatbind): Likewise.

The changle is obviously correct, but I wonder how the bootstrap dies w/o '+'.
It should IMO just prevent the parallelizm and take longer.

Same cryptic error as PR driver/46750.
