Hello,

building NetBSD-current with "-j 2" fails most of the time on my system
in "src/usr.bin/ktruss". The reason is that it shares the dynamically
generated source file "ioctl.c" with "src/usr.bin/kdump" but doesn't
(reliably) wait until the file has really been created.

I can think of two ways to fix this:

1.) Insert a ".WAIT" between "kdump" and "ktruss" in "src/usr.bin/Makefile".

2.) Prefixing the name of the created file with "${PROG}-":

Is there a better way to fix this? Will the second patch increase the
size of the "/rescue" binary?

	Kind regards
