Enabling the config only adds the workaround which causes the kernel to
be a bit bigger (adds -maccumulate-outgoing-args) and does not break the
kernel. When we have the test, we wont need to add this workaround if
the test passes.

This is still a new feature, and until we are sure its safe, we should
have it as an option.

There's lots of things in the kernel that will break with
all{yes,mod}config. I know, because I keep hitting them with my
randconfig tests.
