[U-Boot] [PATCH] Makefile: change LIB to LIB-y

[Daniel Schwierzeck <daniel.schwierzeck@googlemail.com>]

Use LIB-y and LIB-$(xxx) for appending libraries. Also allow appending
to LIB-y in sub-makefiles.

The top Makefile and the SPL Makefile have lines like those:

ifneq ($(CONFIG_AM33XX)$(CONFIG_OMAP34XX)$(CONFIG_OMAP44XX)$(CONFIG_OMAP54XX),)
LIBS-y += $(CPUDIR)/omap-common/libomap-common.o
endif

ifeq ($(SOC),mx5)
LIBS-y += $(CPUDIR)/imx-common/libimx-common.o
endif

This should be done in the arch/CPU/SoC specific sub-makefiles to
keep the top Makefiles clean. This patch also allows adding of new
arch/CPU/SoC specific libraries in the future without touching
the top Makefiles.
