Bug 1426555 - Make autospider builds use --enable-stdcxx-compat on Linux only. r=sfink

Some of the variants are multi-platforms, and having
--enable-stdcxx-compat in their definition will break when the option is
moved over to python configure.

While here, prepare for --enable-stdcxx-compat actually doing something
(it currently doesn't), by adding an exception for it in
check_vanilla_allocations.py.
