If F2FS_FS is modular, enabling the compressions options
F2FS_FS_{LZ4,LZ4HZ,LZO,LZORLE,ZSTD} will make the (de)compression
algorithms {LZ4,LZ4HC,LZO,ZSTD}_{,DE}COMPRESS builtin instead of
modular, as the former depend on an intermediate boolean
F2FS_FS_COMPRESSION, which in-turn depends on tristate F2FS_FS.
Indeed, if a boolean symbol A depends directly on a tristate symbol B
and selects another tristate symbol C:
tristate B
tristate C
bool A
depends on B
select C
and B is modular, then C will also be modular.
However, if there is an intermediate boolean D in the dependency chain
between A and B:
tristate B
tristate C
bool D
depends on B
bool A
depends on D
select C
then the modular state won't propagate from B to C, and C will be
builtin instead of modular.
As modular dependency propagation through intermediate symbols is
obscure, fix this in a robust way by moving the selection of tristate
(de)compression algorithms from the boolean compression options to the
tristate main F2FS_FS option.
