kconfig now detects symbol dependency errors and warns about them.
E.g.:

warning: (NET_DSA && NET && EXPERIMENTAL && !S390 || MACB && NETDEVICES && NET_ETHERNET && (AVR32 || ARCH_AT91SAM9260 || ARCH_AT91SAM9263 || ARCH_AT91SAM9G20 || ARCH_AT91SAM9G45 || ARCH_AT91CAP9) || IXP4XX_ETH && NETDEVICES && NET_ETHERNET && ARM && ARCH_IXP4XX && IXP4XX_NPE && IXP4XX_QMGR || W90P910_ETH && NETDEVICES && NET_ETHERNET && ARM && ARCH_W90X900 || MIPS_AU1X00_ENET && NETDEVICES && NET_ETHERNET && SOC_AU1X00 || SH_ETH && NETDEVICES && NET_ETHERNET && SUPERH && (CPU_SUBTYPE_SH7710 {{20 lines deleted}}
selects PHYLIB which has unmet direct dependencies (!S390 && NET_ETHERNET)

says that NET_DSA & PHYLIB have some kind of problem.
NET_DSA selects PHYLIB.  PHYLIB depends on NET_ETHERNET, which is not enabled
in this randconfig.  net/dsa code does need PHYLIB code, so PHYLIB symbol should
either drop "depends on NET_ETHERNET" or it should be changed to
	depends on NET_ETHERNET || NET_DSA

Preference?
