Subject: libcxx: Build with the libsupc++ ABI
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=1f8ab1c6406451641c05e8cb1e72f7c173a114a3;p=openwrt%2Fstaging%2Fneocturne.git

libcxx: Build with the libsupc++ ABI

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.
