bug#59566: Fail ’guix time-machine’ (Nov 2021) because libgit2

[zimoun <zimon.toutoune@gmail.com>]

Hi,

Well, I am looking for different past versions of Numpy, so I am trying
commit b9595a7659 from Nov 11, 2021,

    gnu: python-numpy: Update to 1.21.3 and cleanup.

and I just run,

   guix time-machine --commit=b9595a7659 -- help

which returns an error:

--8<---------------cut here---------------start------------->8---
[...]

cannot build derivation `/gnu/store/ss0hz522h5w8bp82d4xz165318qw1yv5-profile.drv': 1 dependencies couldn't be built
guix time-machine: error: build of `/gnu/store/ss0hz522h5w8bp82d4xz165318qw1yv5-profile.drv' failed
--8<---------------cut here---------------end--------------->8---

and the failure is about libgit2. The log reads,

--8<---------------cut here---------------start------------->8---
[...]

refs::rename...........
refs::revparse.................F

  1) Failure:
refs::revparse::date [/tmp/guix-build-libgit2-1.1.0.drv-0/libgit2-1.1.0/tests/refs/revparse.c:31]
  Function call succeeded: error
  no error, expected non-zero return

error: in phase 'check': uncaught exception:
%exception #<&invoke-error program: "./libgit2_clar" arguments: ("-v" "-Q") exit-status: 1 term-signal: #f stop-signal: #f> 
phase `check' failed after 11.5 seconds
command "./libgit2_clar" "-v" "-Q" failed with status 1
--8<---------------cut here---------------end--------------->8---

Well, is it specific to my machine?  Or is it reproducible?
