bug#23077: Perl's closure is too big

[Ludovic Courtès]

"Thompson, David" <address@hidden> skribis:

> If you run 'guix size perl' you will notice that, as of this writing,
> 138.2MiB of Perls' 307.6MiB closure is due to referencing gcc's

I’m not familiar with Perl but I think we should get rid of that
reference—that and also Coreutils, Gawk, Binutils, and more:
