All this stuff is controlled by your config file.  The location
which the compiler wrapper uses for ld-uClibc is defined by
SHARED_LIB_LOADER_PATH.  It defaults to $(DEVEL_PREFIX)/lib, but
should be set to just /lib when building stuff to actually deploy
onto a target system.

The location where 'make install_target' installs stuff is into
$(PREFIX)$(TARGET_PREFIX).  

This is what you probably want to do...

       (cd $(UCLIBC_DIR); ln -fs extra/Configs/Config.$(ARCH) Config); \
	$(MAKE) CROSS=$(CROSS) DEVEL_PREFIX=$(BUILD_DIR) SYSTEM_DEVEL_PREFIX=$(BUILD_DIR)/usr \
	    SHARED_LIB_LOADER_PATH=/lib KERNEL_SOURCE=$(KERNEL_DIR) -C $(UCLIBC_DIR); \
	$(MAKE) CROSS=$(CROSS) DEVEL_PREFIX=$(BUILD_DIR) SYSTEM_DEVEL_PREFIX=$(BUILD_DIR)/usr \
	    SHARED_LIB_LOADER_PATH=/lib KERNEL_SOURCE=$(KERNEL_DIR) -C $(UCLIBC_DIR) install; \
	    ln -fs $(BUILD_DIR)/include $(BUILD_DIR)/usr/include; \

You might also want to check out how this is done using the buildroot
example system for inspiration
