I think it's compilers.xml.

In the version supplied with GPRBUILD GPL 2014, at line 663 there's a
section <runtimes/> which, AFAICT, looks in
$prefix/lib/gcc/$target/$version/for:

(a) a directory adalib/; or
(b) a file ada_object_path containing a line beginning rts-; or
(c) a directory rts-*/adalib.

Unfortunately, a few lines above there's a section <version/> which runs
gnatls -v to find the version.

gnatls seems only to recognise option (a) above (it will handles the
other choices when you supply --RTS=, but gprconfig doesn't).
