[OpenWrt-Devel] [PATCH 1/2] libcxx: Build with the libsupc++ ABI

[Rosen Penev]

Allows proper exception handling. This includes removing unimplemented
warnings.

File size increased as a result:

Before:

182874

After:

211006

On mipsel_24kc.

Note that this requires libsupc++ anyway. It's specified in g++-libcxx.
