   IIUC, that's not because of the commit. Even earlier it was the same. 
Because that's how Makefile reads and updates the variables. Now that .gzip is 
listed last in the make file, it defaults to .gzip when all options are set. 
Otherwise it would default to .lz4  or .lzo before lz4 was introduced.

   I don't get it. You mean one option for build time compression and another 
for run time compression? Shouldn't those two be exactly same?
