The configure script will just silently ignore it. That said, you mentioned you used --without-long-double-128 which is the correct way to get a 64-bit long double, so there does seem to be a problem here. I'm adding Alan and Mike to the CC list here for their input on how this is all supposed to work. Given you disabled multilib and forced 64-bit long double, I don't know why libgcc has any 128-bit long double usage.
