You can see here:

https://github.com/python/cpython/blob/master/Makefile.pre.in#L708

that regen-importlib is building a binary from .o files which are built from .c and .h files, which are, at the same time, regenerated by other regen- targets.

This does cause build errors in heavily parallelized builds, we've been seeing it regularly in Yocto Project lately:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=12596

I tried to see if I can easily correct target dependencies in the makefile, but couldn't figure it out. So, a workaround, for us, would be to issue 'make regen-importlib' ahead of other things:

    make regen-importlib
    make regen-all
