For my use, xz -9 is far too slow for anything except the
final "make dist" I run just prior to a release.

For a release, I run this, via one of the
alpha, beta or stable targets in gnulib's

  $(MAKE) dist XZ_OPT=-9ev

Is it possible to setup this to be the default inside makefiles?
(I use make dist only for the final release...)

Some of us use 'make distcheck' regularly as a test case, and for periodic development snapshots.

Since Automake passes through makefile content, it is easy enough to add a project-specific 'make release' target which adds the XZ_OPT option and invokes 'make dist' or 'make distcheck'. Overriding an already set makefile variable is likely not portable.
