It should be disabled for all uclibc based arch/distro combo's
and the change should go to gcc-<version>.inc files as in my original
patch.
Yes, I agree with you.
My proposal is to keep the effect of my patch as small as possible. For I
have not validated other platforms, so I can not disable it this way. I
will try it as soon as possible, if it did has the same problem on other
platform, I will fix the patch.
By the way, on arm, mips platform, there is no such problem. I have not
figured our why it does not occur on the platforms.
