            Bug ID: 9576
           Summary: External tree with BR 2016.11 does not work anymore
           Product: buildroot
           Version: 2016.11
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
          Assignee: unassigned at buildroot.uclibc.org
          Reporter: outtierbert at gmail.com
                CC: buildroot at uclibc.org
  Target Milestone: ---

Hi all,

I am using an external tree with buildroot. My external tree is in a seperate
git repository and the buildroot source is fetched as a git submodule:

./
??? board
??? ??? board definitions...
??? buildroot
??? ??? arch
??? ??? board
??? ??? boot
??? ??? CHANGES
??? ??? Config.in
??? ??? Config.in.legacy
??? ??? configs
??? ??? COPYING
??? ??? DEVELOPERS
??? ??? dl
??? ??? docs
??? ??? fs
??? ??? linux
??? ??? Makefile
??? ??? Makefile.legacy
??? ??? output
??? ??? package
??? ??? README
??? ??? support
??? ??? system
??? ??? toolchain
??? Config.in
??? configs
??? ??? my_defconfig
??? ??? several_defconfig
??? external.desc
??? external.mk
??? package
??? ??? custom package 1
??? ??? custom package 2
??? README.md

This tree was working fine with buildroot 2016.08. To compile, I go into the
/buildroot directory and run: make BR2_EXTERNAL=../ my_defconfig
O=output/my_output and then make O=output/my_output

I followed the buildroot user manual on how to adapt an external tree for
buildroot 2016.11. I created the external.desc file and changed every reference
to $(BR2_EXTERNAL) to $(BR2_EXTERNAL_MY_EXTERNAL_TREE_PATH). Howver, now
building does not work anymore. I get an infinite loop when making like in the
snippet below. Can you help me diagnose the problem?
