It seems that it early stages of 9.6 cycle there was another approach
taken to improve readability of this Makefile - just all common code
put into one C file. So there is no need for SCRIPTS_COMMON variable,
because its name is longer than name of common.o which would be its sole
contents.

Note that said commit (91f3ffc5249) is not limited to rearranging
makefile. It also changes a lot into C code itself. So it is not a
question of reverting commit - it is making new commit, which reverts
changes in just one file.
