Okay that's fine. Very sorry for the delay... Since I found out that there was
no emergency I got back to my work and basically forgot about your question xD

GNU Boot unfortunately can't support x220 since it requires nonfree software to
work at all. One day, perhaps...
So basically what I did been inspired by the work of Timothy Sample from 2018,
reworked to be able to build the current GNAT version.
To build GNAT 11.4.0 on Guix System I created five packages:
1. gnat-debian:
It involves downloading pre-built binary packages from Debian (using version
4.9.2).
The downloaded .deb packages include both GNAT and GCC components.
These components are extracted, patched, and set up to create a minimal GNAT
environment, which can be used to compile Ada code.
The unpack phase extracts .deb archives and patches binaries, making them
suitable for Guix.
The install phase consolidates the libraries into a usable state.
This stage gives us a working GNAT compiler (gnat-debian), which can be used
in subsequent stages.
2. gnat-boot0:
This package builds GCC 11.4.0 with Ada support (c, c++, ada) using the GNAT
compiler from the previous stage (gnat-debian). The gnat-debian compiler is
listed as a native-input, meaning it is used to compile this stage.
The output is a version of GCC 11.4.0 that includes the GNAT Ada compiler,
bootstrapped from the gnat-debian compiler.
3. gnat-final:
This package refines the GNAT compiler produced in gnat-boot0.
It uses the gnat-boot0 compiler as its input to create a final GNAT 11.4.0
compiler.
This stage ensures that the compiler is built with itself, confirming that
the bootstrapping process is complete.
I'm not entirely sure it's mandatory but I saw such process for building GCC
in commencement.scm.
4. gnat:
This package represents the GNAT 11.4.0 compiler that users would install. It
is built using the gnat-final package and with multilib enabled (since I need
that to build memtest86+ for example, but I did not find yet how to use
that).
5. gnat-toolchain:
This package wraps gnat into a complete toolchain, making it easy to use (for
example to build other packages like coreboot with 'package-with-c-toolchain'
?).
I don't know if this is something acceptable for Guix, but I needed that to be
able to work at all on my daily driver x)
You can find the ada.scm module attached. Please note that not everything is
perfect and that there may be errors still, but it works for me (tm).
Happy hacking!
