The problem was introduced by commit e6c6a0238291db27ccdaee229bda59d7981a3182.

After the changes from that commit, the AC_PROG_JAVAC_WORKS macro in
configure.ac is not expanded, since it is defined as a "one-shot" macro (with
AC_DEFUN_ONCE) and used internally by AC_PROG_JAVA_WORKS which is expanded
earlier.

When tools are disabled, AC_PROG_JAVA_WORKS does not run, thus JAVAC never gets
defined.
