This idiom may lead to crashes. According to the wiki[1] mixing
libstdc++ and libc++ is only supported when both are linked against
libcxxrt. lang/gcc by default use libsupc++, so you'd have to add
USES= compiler:gcc-c++11-lib
to force the port use devel/libc++. Also, the following wouldn't work
.if ${CHOSEN_COMPILER_TYPE} == "gcc" && ${COMPILER_VERSION} == 49
because COMPILER_VERSION or COMPILER_FEATURES are evaluated against
COMPILER_TYPE, not CHOSEN_COMPILER_TYPE.
