Hello,

In our OBS builds I occasionally see the following build failure with, e.g., -j 2, which seems to hint at a missing Makefile dependency somewhere:

...

Here it built okay, but too late for helloworld.o.

...

Happens for various defconfigs, hard to reproduce.

Simon, you introduced the efi crt0. Any idea what could be going wrong?

It is most likely a race condition due to a missing dependency.

I see that I have two separate rules in Makefile.lib for the crt0 file. I wonder if they can be combined?
