That's one possibility.

No, because autoconf isn't involved into compilation, that would be your
makefiles, i.e. you will have to find a way inside of your makefiles if
using pure autoconf.
In case you are using automake, adding AM_CONDITIONAL inside of your
configure.ac and using them inside of your Makefile.am's probably is
what you are looking for.
