Bug 1255312 - Limit the options we pass down to old-configure. r=chmanchester So far, we've been passing down all configure_args from mozconfig as well as every flag appearing on sys.argv. This is overly broad and causes problems for some options, like --enable-application. However, we don't need all these options to be passed. For the top-level old-configure, we need to pass the flags it can handle, as well as the flags that we want passed down to js/src/configure. For js/src/old-configure, we only need to pass the flags it can handle. The flags an old-configure can handle is defined by the list of flags in @old_configure_options. The list of flags to pass down to js/src/configure is defined by extra_old_configure_args. And since the mozconfig configure_args are being injected into python configure processing, the list of values we get in old_configure includes the mozconfig configure_args.
