No '-lz' on this command line -- you're not actually asking it to link
against zlib. Thus is doesn't find any of zlib's symbols.

I've no idea what this is about. Perhaps the function pointers in the
jffs2_zlib_comp compressor structure?

mkfs.jffs2 builds fine for me for FR-V uClinux, although that's
ELF-FDPIC not flat. Are the relocations in .rodata actually a problem?
Doesn't m68k have ELF-FDPIC yet?

Something wrong with 'make DESTDIR=/foo install' ?
