Thanks.

In a preboot environment the options selected for the xz_dec module are
ignored. If XZ-compressed kernel is selected, lib/decompress_unxz.c
will enable a BCJ filter for that architecture. An alternative could be
to #undef the CONFIG_XZ_DEC_foo symbols in decompress_unxz.c and then
#define what is needed for the selected architecture, but I think the
current method is OK. See also lib/xz/xz_private.h.
