build: remove libstdc++ backwards-compat

theuni · theuni · commit aa3673064c5c · 2015-02-23T17:56:15.000-05:00
Backwards-compatibility for libstdc++ is not limited to straightforward abi
changes. Symbol visibility also needs to be taken into consideration, and
that really can't be addressed simply.

Instead, just static-link libstdc++ for backwards-compat.
