This is an interface variable, not a configuration option. See
http://ecos.sourceware.org/docs-latest/cdl-guide/language.interface.html
What you probably want to add is a
CYGBLD_DEVS_ETH_ARM_AT91_MULTICAST
which when enabled includes multicast support and implements the
CYGINT_IO_ETH_MULTICAST interface.
