Debian 11 (Bullseye) has a quite a few cross-toolchains in its package repository:
pmunts@PHILIPPI:~$ apt-cache search gnat-10 | egrep '^gnat'

gnat-10-doc - documentation for the GNU Ada Compiler (gnat)
But alr search --full --external-detect gnat_ does not find any of these toolchains, neither before nor after one is installed.
The only workaround I have for now is to generate default.cgpr for a Debian cross-toolchain and manually copy it to an alr project directory.
