This compiler is released in both native and cross-compiler
configurations at
https://sourceforge.net/projects/gnuada/files/GNAT_GCC%20Mac%20OS%20X/6.1.0/
From the native compiler README:
Compilers included: Ada, C, C++, Objective C, Objective C++, Fortran.
Tools included:
Full GPL:
ASIS, AUnit, GDB, and GNATColl from GNAT GPL 2015.
GPL with Runtime Library Exception[1]:
Gprbuild from the public Git repository[2] at commit
11f9b58c0283586f4fb134ff8c022f1117b58223
XMLAda from the public Git repository[3] at commit
8a9536bf161125cb1e12da376e8d7b51f1b33677
(I would have included GNATColl here, but it now relies on "libgpr";
waiting for GNAT GPL 2016 to see what this means.)

========================================================================
From the arm-eabi compiler README:
This is GCC 6.1.0, rebuilt as a cross-compiler from Mac OS X to
arm-eabi (specifically, the Cortex-M3 as found on the Arduino Due[1]
and the Cortex-M4 as found on the STMicroelectronics[2] STM32F4
Discovery and STM32F429I Discovery boards).
The compiler comes with no Ada Runtime System (RTS). See the Cortex
GNAT Run Time Systems project[3] for candidates.

It turns out that the native-2015 README makes a claim that I in fact
failed to fulfil. I've updated it and uploaded a patch for manual
application, if needed; only if you're going to be building a
relocatable library (e.g. your own version of GNATColl).
The relevant section of the updated README says
Library names
.............
The ld error "library not found for -lgnat-6.1" will be encountered
when using gprbuild to link a relocatable library (ordinary
relocatable links should be OK). The reason is that the GCC build
process only generates libgnat-6.dylib, libgnarl-6.dylib, but gprbuild
tries to link against libgnat-6.1.dylib (why it wouldn't just link
against libgnat.dylib I don't know).
You can fix by either of
* installing the necessary symbolic links: in
$prefix/lib/gcc/x86-64-apple-darwin15/6.1.0/adalib,
sudo ln -s libgnat-6.dylib libgnat-6.1.dylib
sudo ln -s libgnarl-6.dylib libgnarl-6.1.dylib
* patch gprbuild's database: download
share-gprconfig-compilers.xml.diff, then in $prefix,
sudo patch -p1 <~/Downloads/share-gprconfig-compilers.xml.diff
