foreign arch build taking too long `guix build -s armhf-linux help`

[Giovanni Biscuolo]

Hi Guix!

I've a x86_64 build machine I configured to build for arm and aarch
architetures this way:

--8<---------------cut here---------------start------------->8---

 (service qemu-binfmt-service-type
          (qemu-binfmt-configuration
           (platforms (lookup-qemu-platforms "arm" "aarch64"))
           (guix-support? #t)))

 (modify-services %base-services
   (guix-service-type config =>
                 (guix-configuration
                  (inherit config)
                       (use-substitutes? #f)
                       (authorized-keys
                        %authorized-guix-keys)))))))

--8<---------------cut here---------------end--------------->8---

This should enable transparent build for another architecture, using no
substitutes.

To test a build I did `guix build -s armhf-linux help`; after several
hours I'm still waiting the build to complete, it seems stuck at this
build stage:

--8<---------------cut here---------------start------------->8---
[...]
/gnu/store/zxgm9xn0dgqfp6dxynklqzr27957qkis-make-boot0-4.2.1/bin/make  
subdir=stdlib -C stdlib ..=../ others
make[2]: Entering directory 
'/tmp/guix-build-glibc-intermediate-2.28.drv-0/glibc-2.28/stdlib'
--8<---------------cut here---------------end--------------->8---

and this process:

--8<---------------cut here---------------start------------->8---
 /gnu/store/sw2rrqmjij73wcy3ajd47ypvmzh12yz6-qemu-3.1.0/bin/qemu-arm 
/gnu/store/43ljk0rxwxl4c9msr4b9xwihhw6fak8v-bootstrap-binaries-0/bin/rm -f  
/tmp/guix-build-glibc-intermediate-2.28.drv-0/build/stdlib/drand48.os.dt
--8<---------------cut here---------------end--------------->8---

The process run time taken from `top` now is 796:50.68 :-O

That file is still there and it seems it's not removed:

--8<---------------cut here---------------start------------->8---
~$ sudo ls -lah 
/tmp/guix-build-glibc-intermediate-2.28.drv-0/build/stdlib/drand48.os.dt
-rw-r--r-- 1 guixbuilder01 guixbuild 5.7K Jun 11 04:02 
/tmp/guix-build-glibc-intermediate-2.28.drv-0/build/stdlib/drand48.os.dt
--8<---------------cut here---------------end--------------->8---

Looking at /var/log/guix-daemon.log does not help.

Any hint about what's going on here and/or understanding why that
process is stuck removing that file?

Thanks! Gio'.
