No problem! I only knew about the revert because I was investigating the
static build faiulures, and also considered the bump... ;-)

You can start with any of those defconfig:

    static based on uClibc:
    http://autobuild.buildroot.org/toolchains/configs/br-arm-full-static.config

    based on musl (but need to manually set static):
    http://autobuild.buildroot.org/toolchains/configs/br-arm-cortex-a9-musl.config

Save them locally, and run:

    make BR2_DEFCONFIG=/path/to/where/you/saved/br-arm-full-static.config defconfig
    make menuconfig
        -- enable protobuf
        -- exit
    make protobuf

(Similarly for the musl build, but you need to enable static-only in the
menuconfig).

OK, great! Thanks! :-)
