https://www.gnu.org/software/hurd/toolchain/cross-gnu.html describes a 
script for building a cross toolchain for Hurd.  I don't know how current 
it is.

Yes, we should have such support in build-many-glibcs.py for checking out 
and building whatever's relevant from MIG / GNU Mach / Hurd / Hurd 
libpthread and building glibc for Hurd.  I think that makes sense even 
without functional Hurd support in glibc; it will just fail in all builds 
(like existing broken configurations) and then once the Hurd support in 
glibc is fixed, we'll see it change from FAIL to PASS in the results from 
the bots.

(Should Hurd libpthread actually be part of glibc rather than a separate 
package?)
