Hello, thx for refreshing the patch.

being that we have  two vars:
XZ_COMPRESSION_LEVEL ?= "-e -9"
LZMA_COMPRESSION_LEVEL ?= "-e -9"

wouldn't it better to use   XZ_COMPRESSION_LEVEL?
Remember (man xz) that lzma-utils '-9' is equivalent to xz-utils '-8'
in terms of dictionary/ram needed for decompression.

Regards

Andrea
