The -stdlib arg *isn't* appended to configure.cxxflags; it's added to the CXXFLAGS environment variable in configure_main; ports have no opportunity to inspect or modify this value. I had to manually add code to the pure portgroup to handle configure.cxx_stdlib because of this. Any port which sets "use_configure no" because it does not use a standard build system like autotools or cmake will be similarly affected.

Sorry, I said "augment" instead of "append to" intentionally, to differentiate between actually changing configure.cxxflags and augmenting it before setting CXXFLAGS.
