From: Janneke Nieuwenhuizen <janneke <at> gnu.org>
To: 74290 <at> debbugs.gnu.org
Subject: [PATCH v4 05/58] gnu: cross-libc: Support cross-building for the
 64bit Hurd.
Date: Sun, 24 Nov 2024 08:54:28 +0100

* gnu/packages/base.scm (glibc)[arguments]: When building for the Hurd, in
phase "create-machine-symlink", do not assume CPU is i386, also cater for
x86_64.
* gnu/packages/cross-base.scm (cross-libc*)[arguments]: Likewise.
