Upstream provides a few options to control features being built. I'd like to disable the filters that are not used in any default configuration. What I'm thinking of are the following options: --enable-encoders=lzma1,lzma2 --enable-decoders=lzma1,lzma2 --enable-match-finders=hc3,hc4,bt4 --enable-checks=crc32,crc64 This has two goals: to reduce size of xz-utils, and to prevent people from using custom profiles to create non-portable .xz files.
