Subject: Re: [PATCH] MIPS: Allow R6 compact branch policy to be left
 unspecified

I was wondering if we should simply probe for the availability of the
GCC option and not use it, if using an older GCC, then change the
help text for the option accordingly.  This approach would allow
make randconfig or similar to work as expected with older compilers.
