Building -current on sparc64 fails?

[Darren Reed <darrenr%netbsd.org@localhost>]

I started with Makefile.local.inc containing:

DESTDIR=/current
MKMAN=no
MKSHARE=no
NOINCLUDES=yes
MKX11=no

ran...
# ./build.sh -j4 -T /current/tooldir build
...
it produced the error below, removed "NOINCLUDES" line from 
Makefile.local.inc,
followed that with

# ./build.sh -u -j4 -T /current/tooldir build
...
