Sorry for showing up unexpectedly. I just noticed the few things. I hope it's not too much bikeshading. I do a lot of Makefile programming and have also integrated the qubes build system in to my monorepo, and I often stumble about suboptimal Makefiles. |

This runs into an xl bug: xl doesn’t check for write errors on stdout. The following helps but does not fix the problem:
