[Buildroot] linux26 compile error

[Frank Kujawski]

That gets me one step further, but it is failing trying to apply a patch:

$(LINUX26_DIR)/.patched: $(LINUX26_DIR)/.unpacked
        toolchain/patch-kernel.sh $(LINUX26_DIR) $(LINUX26_PATCH_DIR) touch $@

surrounding the part that defindes the $(LINUX26_DIR)/.patched target. 
You have LINUX26_VERSION matching LINUX_HEADERS_VERSION and therefore all
the code inside the "ifneq" is skipped.  This results in the make error:
"no rule to make target"
>>> If you do not need to build a kernel, the simplest fix would be to disable
the linux26 target entirely (turn off BR2_PACKAGE_LINUX). I'm not sure why
the ifneq is there in the first place.  It may have made sense prior to
the BSP patch that was recently added. -R

this looks to me to be an incomplete BSP patch at the moment. Attached is my
temporary fix until this is completed.
