There are two small issues I have with this patch:
(1) I think it should be restricted to GCC with an appropiate comment of
what this is a workaround for. Clang seems to behave a lot more sensible
out of the box. If there are CPU models with a different base alignment
and the user asked for one of them as optimisation target, it should be
honored IMO.
(2) This should not touch CFLAGS, but COPTS.
