Subject: silence c++ abi warning
X-Git-Tag: v1.8.0~379
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=00238b7c01b599627af12cfb908137013b544590;p=libvpx

silence c++ abi warning

Linking c++ libraries built with gcc 6 and gcc 7 on arm
generates some warnings because of incompatibilities between those
compilers:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=77728

libvpx does not generate a c++ library. C++ is only used for examples and tests.
