[PATCH] make: add distcheck-fast target

[PATCH] make: add distcheck-fast target

[Matthias Maennich]

The default compression flag defined by automake via GZIP_ENV is --best.
That is pretty expensive for when you just want to make sure your change
is done properly to pass 'make distcheck'.

Hence add a convenience target 'make distcheck-fast' that sets GZIP_ENV
to --fast and runs distcheck with that.

On my machine, this almost cuts the 'make distcheck' time in half:

 distcheck       4min 40s
 distcheck-fast  2min 32s

This is not invasive as it does not change the existing distcheck
target.

It also saves minutes on my machine. So I am using make distcheck-fast
on the buildbot workers too now. Hopefully that will speed up things
there too.

Thanks,

Mark

P.S. The ppc64 and ppc64le workers are down at the moment. They should
hopefully get back online soon (and go through the backlog).
