Actually,

   gprconfig -v --target=<your target>

or

   gprconfig -v --target=all

Gprconfig looks for a compiler and a runtime. If it finds {target}-gcc
it runs -dumpmachine to find the version, then looks for runtimes in (at
least) lib/gcc/{target}/{version}; first in adalib/, then via
ada_object_path, then via rts-*/.
