"make dist-get-tag" string is different from the tag that "make dist-release" sets

Since a few days the string "make dist-get-tag" for me does not match the tag any more that "make dist-release" sets. From a very quick check I believe this is caused by 10c3f06d ("redhat: introduce RELEASE_LOCALVERSION variable") from @jstancek and happens if one sets DISTLOCALVERSION, but does not set RELEASE_LOCALVERSION to the same string; I found this confusing and it broke my scripts.

No big deal, but feels wrong and I guess others will run into similar problems. All in all I found this confusing (even after reading the commit msg I still don't really understand what to do; just set DISTLOCALVERSION, switch to RELEASE_LOCALVERSION, or make both the same value? [I guess it's the latter, but that somehow feels wrong])
