Two things...

1. Your makefile helped, but the static 'erase' binary is nearly 2MB
(0.5MB stripped); I need this for the target and can't afford that much
space.  When I add '-shared' to CFLAGS, 'erase' is down to a manageable
size, but then I see that the libc.so.6 (libc-2.2.5.so) that it needs is
over 5MB (1.6M stripped).  Still too big.  Are there other solutions for
erasing or for library?

2. Also, I'm still getting...

"undefined reference to: 'cpu_to_je16'" and 
"undefined reference to: 'cpu_to_je32'"

errors when building eraseall.c.  It seems it uses these, but the only
place I see them defined (as macros) is in mkfs.jffs2.c.  I could always
just duplicate those from mkfs.jffs2 and put them into eraseall, but I'm
wondering if there are other issues involved.
