I have to, for qemu. In some cases the new compilers don't work with
old kernels (eg sparc) and I prefer to use a single compiler for all
kernel versions, in other cases newer versions of gcc have trouble (sheb),
and for xtensa building a compiler that works for a given hardware model
is tricky so I try to avoid it as long as I can.
