It seems like you're mixing up two different things. The JAVA, LISP
and PYTHON primaries are all used for processing interpreted languages
into a byte-code form. _LOG_COMPILER is for running tests. So if you
need to use bytecode-compiled Python as a test case, and if you need
to put something before the filename of the test case in the command
to run it, you need both.

The AM_ prefix is only for user variables. ext_LOG_COMPILER are not
user variables. There are a handful of other Automake variables like
this: COMPILE, LINK, LDADD.
