(Changes from v0: 'align "lzo" with the rest of the suffixes/tool names' as
Sergei suggested.)
The commit "lib: add support for LZO-compressed kernels" has been merged
into linus' 2.6.33-rc4 tree, so, It is time to add the support for MIPS.
NOTE: to enable this support, the lzop application is needed.
