4.999.8beta shouldn't be used for anything, because it has a data
corruption bug. It might be patched in some distros that didn't want to
upgrade the whole package, so the version number doesn't tell
everything.

I think that 4.999.8beta is not worth supporting, but just in case you
still do: People can use XZ_OPT even if it is not put there by Automake.
Then the default level will be -6. If you want -9 to be the default,
maybe this is OK:
xz_preset= ; if test -z "$XZ_OPT"; then xz_preset=-9; fi; \
tardir=$(distdir) && $(am__tar) | xz $$xz_preset >$(distdir).tar.xz
