[libvirt] [PATCHv2] build: increase xz compression level

Increase the default compression level to 9 from 6. This also increases decompression memory requirements from 9 MB to 65 MB.

This is a make variable, not shell, so 'export XZ_OPT' is not relevant AFAICT. ACK if that line is removed.

It does not work without export. I don't know whether it's needed to propagate the value to a sub-Makefile or automake expects it to be a shell variable when executing the command: tardir=libvirt-2.0.0 && tar --format=posix -chf - "$tardir" | XZ_OPT=${XZ_OPT--e} xz -c >libvirt-2.0.0.tar.xz Jan
ACK if that line is removed.
