This was not noticed until now because:
1/ The older Blackfin toolchain doesn't have libatomic, so it didn't
provide the atomic operations that protobuf needs, so protobuf was
never built.
2/ The ARM Cortex-M toolchain is static-only, and protobuf requires
dynamic library support.
So it's only with the new Blackfin toolchain, which is based on gcc
6.x (and therefore provides libatomic) and is FDPIC-based (and therefore
has dynamic library support) that this problem appeared.
Since protobuf already has a BR2_PACKAGE_PROTOBUF_ARCH_SUPPORTS option,
we use it to add the BR2_USE_MMU dependency (which is architecture
related), which avoids the need to propagate the dependency.

[Thomas:
- move the BR2_USE_MMU dependency under
BR2_PACKAGE_PROTOBUF_ARCH_SUPPORTS and remove the propagation to
reverse dependencies of protobuf, since they already depend on
BR2_PACKAGE_PROTOBUF_ARCH_SUPPORTS.
- improve commit log.]

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
