Suppress error about mismatching C++ ABI version

Forwarded: no
Last-Update: 2022-07-18

In practice, the differences between recent ABI versions don't seem to be
incompatible since they apparently only affect obscure corner cases.  So
suppress this error so we don't have to rebuild the entire wx world in one
go.
