At present, ISA bus support is always included in the build for all targets. However these days there are a number of targets that have never had ISA, and even more where many of the individual machines don't have ISA.
Unfortunately there are some awkward dependencies in the core code on ISA, although b19c1c0 "isa: remove isa_mem_base variable" did already remove one. This series engages in some yak shaving to make the necessary dependency cleanups, then make inclusion of ISA support optional. Given the date, this is obviously aimed at qemu 2.4, not 2.3.
