Hello,

ludo <at> gnu.org (Ludovic Courtès) skribis:

I went ahead and pushed these two patches as
93c333895a4e2dc9baabec8ade60d9d2ac0a91e2 and
e4297aa8b95cefa32e2595ce58886fc03b0561f7.

I modified tests/debug-link.scm compared to what I posted such that it
would skip tests that require %bootstrap-gcc when networking is lacking.

Thanks for your feedback,
Ludo’.
