I still don't understand why you can't use origin/baseline instead of the
verbatim and volatile SHA1?

$ wget
'http://hydra.nixos.org/build/1458856/download/3/glibc-2.14-375-gaac1330.tar.xz'
$ xz -d < glibc-2.14-375-gaac1330.tar.xz | tar -x
$ find glibc-2.14-375-gaac1330/ -name tlsdesc.sym
glibc-2.14-375-gaac1330/sysdeps/x86_64/tlsdesc.sym
glibc-2.14-375-gaac1330/sysdeps/i386/tlsdesc.sym
But <http://hydra.nixos.org/build/1458856/log/raw> says: ``patching file
sysdeps/mach/hurd/i386/tlsdesc.sym''. I guess this is for you to debug.
