makefiles: dist and rpm target

Basic support for upstream 'build' of rpm packages.
Make spec file generated.

2 new simple targets:

make dist  - create LVM2.MAJOR.MINOR.PATCHLEVEL.tgz  from git files.

make rpm   - some generic rpmbuilder using spec files.
             Create packages in build/ subdir.
             DO NOT USE created rpms in any distribution!

+%description
+LVM2 includes all of the support for handling read/write operations on
+physical volumes (hard disks, RAID-Systems, magneto optical, etc.,
+multiple devices (MD), see mdadd(8) or even loop devices, see
+losetup(8)), creating volume groups (kind of virtual disks) from one
+or more physical volumes and creating one or more logical volumes
+(kind of logical partitions) in volume groups.
