Hi,

As discussed on IRC, the problem seems to be that, when cross-compiling,
the ‘OUTPUT_FORMAT’ bit in libc.so is wrong (“elf64-little” instead of
“elf64-littleaarch64”).  This, in turn, seems to be due to a regression
in how glibc’s build machinery computes that value, which is fixed by
this patch:

  https://sourceware.org/pipermail/libc-alpha/2021-July/128333.html

I haven’t had feedback from upstream yet but I’ll apply it soonish in
Guix as it does the job.

Thanks,
Ludo’.
