Just updated to revision 23943. The patch looked liked it would fix the
issues I have with compiling mtd. But, no good I still get errors.

In order to get mtd to build correctly I have to patch mtd.mk as
follows:

$(MTD_BUILD_TARGETS): $(MTD_DIR)/.unpacked
	mkdir -p $(TARGET_DIR)/usr/sbin
	$(MAKE) CFLAGS="-I. -I./include -I$(LINUX_HEADERS_DIR)/include
-I$(STAGING_DIR)/usr/include $(TARGET_CFLAGS)" \
+		LDFLAGS="$(TARGET_LDFLAGS)" \
		BUILDDIR=$(MTD_DIR) \
		CROSS=$(TARGET_CROSS) CC=$(TARGET_CC)
LINUXDIR=$(LINUX26_DIR) WITHOUT_XATTR=1 -C $(MTD_DIR)

With the patch above the compile output is:

...
/usr/local/arm/4.1.1-920t/bin/arm-linux-gcc
-L/home/bigguiness/buildroot/build_arm/staging_dir/lib

/home/bigguiness/buildroot/build_arm/mtd_orig/compr_lzo.o
/home/bigguiness/buildroot/build_arm/mtd_orig/compr.o -lz -llzo2
...

It appears mtd is using gcc to link the objects and not ld so the
correct flags are not getting passed.
