I noticed that the location of sha1.h moved to a sys/ subdirectory recently.  Since that time, I cannot rebuild the NetBSD toolchain.  I've tried doing things like make clean to no effect.  Please let me know if I'm making a mistake here or whether the toolchain is broken  build.sh output below.
Regards,
