>Description:
build.sh -m macppc64 fails to build coredump.kmod due to
its failure to find and compile arch/powerpc/powerpc/core_machdep.c,
i.e.:

dependall ===> sys/modules/coredump
#    create  coredump/core_netbsd.d
...
#    create  coredump/kern_core.d
...
#    create  coredump/uvm_coredump.d

#    create  coredump/.depend
rm -f .depend

powerpc64--netbsd-gcc: core_machdep.o: No such file or directory

*** Failed target:  coredump.kmod

With MACHINE_ARCH=powerpc64 the Makefile fails to find the
source file in the arch/powerpc/powerpc directory.
>How-To-Repeat:
Do a:

    MACHINE=macppc64 ./build.sh distribution
>Fix:
The following patch to the Makefile in sys/modules/coredump
works around the problem, though I know so little about the
build system that I can't judge whether this is a "fix" or a
"hack-around":
