Thanks to Havard Eidness for pointint out a typo (/ instead of a \) in 
the edit to .../instkernel/Makefile.  I'll repeat the entire section to 
minimize the confusion.

Next, add NSLU2_INSTALL to the compile targets:

$ cd ~/net/src/distrib/evbarm/instkernel/instkernel
$ cp Makefile Makefile.orig
$ nano Makefile

Change the line
MDSETTARGETS= ADI_BRH_INSTALL ${RAMDISK} -
to
MDSETTARGETS= ADI_BRH_INSTALL ${RAMDISK} - \
NSLU2_INSTALL ${RAMDISK} -
