Hi,

the -Wabi option prints a warning as follows:

cc1plus: warning: -Wabi won't warn about anything [-Wabi]
cc1plus: note: -Wabi warns about differences from the most up-to-date
ABI, which is also used by default
cc1plus: note: use e.g. -Wabi=11 to warn about changes from GCC 7

This happens many times while building libstdc++, and as the warning
explains, it is good for nothing, so this patch removes it.


Bootstrapped and reg-tested on x86_64-pc-linux-gnu.
Is it OK for trunk?


No, I don't think we want to simply remove it.

Maybe https://gcc.gnu.org/ml/gcc/2018-06/msg00276.html instead?
