[PATCH 6/8] Makefile: don't use a versioned temp distribution directory

[Ramsay Jones]

The 'dist' target uses a versioned temp directory, $(GIT_TARNAME), into
which it copies various files added to the distibution tarball. A future
patch requires the 'clean' target not to depend on the $(GIT_VERSION)
variable. However, the $(GIT_TARNAME) variable contains $(GIT_VERSION) in
its definition.

Create an '.dist-tmp-dir' directory and copy the various files into this
now un-versioned directory while creating the distribution tarball. Change
the 'clean' target to remove the '.dist-tmp-dir' directory, instead of the
version dependent $(GIT_TARNAME) directory.
