Hi Pierre,

FYI, it looks like you included [email protected] in the CC list of your
last email.  If you do that, I believe it will create a new bug report,
which may not be what you intended to do.

I agree with you.  That said, I don't personally run any aarch64-linux
machines, and I don't plan to investigate the aarch64-linux issue
further right now.

Although I will defer to anyone who actually runs aarch64-linux and
knows better, at the moment to me it seems reasonable to commit a patch
like the one you've proposed in order to ensure that the "guix" package
builds successfully on that platform for the 1.4.0 release.  The fact
that you have successfully built and used various pieces of software on
aarch64-linux with this patch suggests that maybe the current behavior
is OK, after all.

I've made some rather trivial modifications to your patch, mainly to
make it conform to our required ChangeLog format.  If nobody has further
comments, I will commit the attached version to master in about 24
hours.
