It means the build supports async subprocesses. Once upon a time,
several platforms where Emacs could be built did not have this
capability, but nowadays only the DOS build remains without it.
Quite a few of the macros are documented in src/config.in and in
src/m/*.h and src/s/*.h header files. This one is in config.in.
Btw, `select' is not the problem here, because even the DOS build has
it. The issue is whether you have `pipe' and `fork'/`exec' (or some
equivalents thereof), and whether `select' can handle network file
descriptors.
