armel gbs for the #866354 ABI change

[Adrian Bunk <bunk@debian.org>]

#866354 is a libstdc++6 ABI change in gcc 6 -> 7 only affecting armel
caused by the #727621 backport to the stretch gcc (the symbols in the
backport to gcc-6 and in upstream gcc >= 7 are at different versions).

Cases where binNMUs are required are handled in #874124.

Breaks for stretch -> buster upgrades will be handled in #866354.


#873609 is now fixed
gb llvm-toolchain-3.9_1:3.9.1-13 . armel armhf . --extra-depends "gcc-7 (>= 7.2.0-2)"

#866354 gbs
gb afl_2.50b-1 . armel . --extra-depends "libclang-3.9-dev (>= 1:3.9.1-13)"
gb aspectc++_1:2.2+git20170823-1 . armel
gb kdevelop 4:5.1.2-1 . armel . --extra-depends "libclang-3.9-dev (>= 1:3.9.1-13)"
gb libc++_4.0.1-1 . armel
gb llvmlite_0.19.0-2 . armel
gb mesa_17.1.5-1 . armel

# waiting for llvm-defaults transition (see #869602)

Thanks in advance
Adrian
