Hi,

I’m having problem to build recent 14-CURRENT/aarch64 as of 6d2648bcaba9b14e2f5c76680f3e7608e1f125f4:

--- cddl/lib/libuutil__L ---
make[4]: make[4]: don't know how to make uu_dprintf.c. Stop
make[4]: make[4]: don't know how to make uu_open.c. Stop
`uu_alloc.c' is up to date.
`uu_avl.c' is up to date.
`uu_dprintf.c' was not built (being made, type OP_DEPS_FOUND|OP_MARK, flags REMAKE|DONE_WAIT|DONE_ALLSRC|DONECYCLE)!
…

The build is performed with pristine /usr/obj

Any hints, please?
Thanks
otis
