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.
