>Description:
Symbol _nfsbootdevname is defined in src/sys/nfs/nfs_boot.c only if NETHER
is non-zero.  But src/sys/arch/mac68k/mac68k/autoconf.c references the
symbol if NFSCLIENT is defined, regardless of NETHER.  This results in an
undefined symbol in the linker if the kernel was built with NFSCLIENT but
without any Ethernet interface.
>How-To-Repeat:
See above.
>Fix:
The following patch modifies autoconf.c to not reference the symbol unless
an Ethernet interface was configured.  This is probably not the best 
solution, but at least it let's you build the kernel.  :)

A more correct solution would probably be to define the symbol whenever
NFSCLIENT is selected, regardless of whether an Ethernet interface is
configured.
