The SO_RCVLOWAT option is defined as 18 in the selftest header, which matches the generic definition. However, on powerpc, SO_RCVLOWAT is defined as 16. This discrepancy causes sol_socket_sockopt() to fail with the default switch case on powerpc.
This commit fixes by defining SO_RCVLOWAT as 16 for powerpc.
