The source file sysdeps/mach/hurd/bits/errno.h is generated from sources 
including some headers from those components.  I don't know how often 
those may change in ways that affect that header, or what versions the 
current header corresponds to, but in any case it's a known issue that 
there are several generated files in the source tree that 
build-many-glibcs.py doesn't yet touch on checkout.

Regarding libpthread, I don't propose build-many-glibcs.py support for a 
separate libpthread component; what's relevant is whatever version goes on 
the sthibaul/hurd-builds branch of glibc (set up to build without the old 
add-ons mechanism), and in due course on master.
