    Revert "toolchain/gdb: update to version 8.0.1"
    
    Since version 8.0, gdb requires at least gcc 4.8. Unfortunately some of
    the buildbot slaves don't meet this requirement, and fail to build LEDE
    after the gdb upgrade. Revert to the previous gdb version for now.
    
    This reverts commit 592abe9ef53f921554d48085d6482d4507b3e142.
