Re: [Ada] Set Always_Compatible_Rep to False everywhere


> Agreed, let's do that for starters.

And a small follow-up change.


2016-10-19  Eric Botcazou  <ebotcazou@adacore.com>

	* system-linux-armel.ads: Rename into...
	* system-linux-arm.ads: ...this
	* gcc-interface/Makefile.in (ARM/Android): Adjust to above renaming.
	(ARM/Linux): Likewise.
	(Aarch64/Linux): Likewise.
