bug#67157: gcc-toolchain@4.8.5 not available on the official substitute servers

["Frédéric Mahé" <frederic.mahe@cirad.fr>]

Hi, I am new Guix user.

So far, I've been using Guix to create one-of environments with 
different versions of GCC and clang. My first goal is to compile a C++ 
project with different compiler versions and to check that everything is 
ok. For instance:

guix shell gcc-toolchain@13

It works great, except for GCC 4.8.5 (the oldest version I aim to 
support for my C++ project). That version seems to be the only 
gcc-toolchain version not available on the official substitute servers 
(need to compile/build), and compilation fails on my machine.

Is the absence of a x86-64 GNU Linux GCC 4.8.5 build deliberate? I can 
imagine that this old version is not a priority anymore. Nonetheless, it 
is still very frequent in the wild, at least until the end-of-support of 
CentOS 7 next year.

Thanks for your help,

Here are the command used and the complete log:

guix shell gcc-toolchain@4.8
hint: Consider passing the `--check' option once to make sure your shell 
does not clobber environment variables.

The following derivations will be built:
