    gnu: commencement: Build fix for python-boot0 on the Hurd.
    
    Unlike during a non-chroot'ed build on Debian/Hurd, there is no 
/usr/include.
    
    * gnu/packages/commencement.scm (python-boot0)[arguments]: When building on
    the Hurd, add `fix-regen' stage to correct a reference to "/usr".
