I'm doing a make build on -current/sparc with MAKEOBJDIRPREFIX set.
After fixing make(1) so that it does a chdir(${.CURDIR}) before
invoking ${.MAKE} all went well... but depend in libc fails because
lib/libc/net/Makefile.inc includes generated files nslexer.c and
nsparser.c in SRCS and has no beforedepend target to cause them to be
generated. 

Is the correct solution to put nslexer.l and nsparser.y in SRCS
or add a beforedepend target?  I've done the former - should know soon
if it works :-)
