bug#60589: guix build --keep-going (-k) not always honored

[Maxim Cournoyer]

Hi,

I just encountered the following, which is puzzling:

I updated ruby-asciidoctor, and was attempting to rebuild its
dependents, with something like:

$ ./pre-inst-env guix build --keep-going weechat ccextractor

Which produced:

--8<---------------cut here---------------start------------->8---
make[2]: Leaving directory '/tmp/guix-build-ccextractor-0.88.drv-0/source/build'
make[1]: *** [CMakeFiles/Makefile2:129: lib_ccx/CMakeFiles/ccx.dir/all] Error 2

This is not the expected output when using --keep-failed; I would have
expected the build to complete then guix to report about the failure,
but it appears to abort without building weechat.
