David Leverton writes about adventure/crc.c:

The 'adventure' game from the games-misc/bsd-games-2.13 package crashes
when saving the game on AMD64 (and probably other 64-bit systems, but I
haven't checked).  Find attached to fix this.

About utmpentry.c:

the utmpx structure defines the ut_tv member a little differently on
64bit hosts so that a 32bit and 64bit structure can be shared.  So the
ut_tv is a custom 32bit structure rather than the native 64bit timeval
structure.  Work around is to assign the submembers instead.

following steps:

- Create a new x86_64 VM using QEMU.
- Use
  https://ftp.gnu.org/gnu/guix/guix-system-install-1.2.0.x86_64-linux.iso.xz
  to install Guix System 1.2.0 in the VM.
- Run: guix pull --no-substitutes --commit=662e7e28d576ada91fc9dec7d27c100666114f03
- Run: guix build --no-substitutes --target=powerpc64le-linux-gnu bootstrap-tarballs

With the exception of gcc-static, all bootstrap binaries contained in these
tarballs can be built reproducibly.  Unfortunately, gcc-static is not always
reproducible when everything is built from source on separate machines.
Despite investigation efforts, the cause remains unclear, so we have decided
to move forward with these binaries to unblock further bootstrapping work.
For details, see &lt;https://bugs.gnu.org/41669&gt;.
