I would recommend using the system libstdc++ and system libgcc_s

The FSF libstdc++ is, I believe,
binary incompatible with the system one, and since system libraries
use the system one there is no way to guarantee that you're using the
right one for your code.
Okay, so uh, how do you propose to do a full bootstrap and test if you
can't test the built libstdc++?
In particular, since the testsuite sets the dyld library path, won't
this cause the system libs to try to use the libstdc++ you just built,
which is incompatible?
(This is mildly rhetorical, since this is indeed what happens, at
least as of 9A377a).
