config/toolchain: force use of sysroot if OBSOLETE is not set

Use of the sysroot is highly recommended, and the non-sysroot case is
both obsolete and not widely tested.

Before the non-sysroot case can go away, deprecate it.

This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,
yann@2173
     5
MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.5.1,
yann@2173
     6
for e500v2 DPFP support) and will generate appropriate dual-precision
yann@2173
     7
floating point instructions by default.

Note: If building a Linux kernel with this toolchain, you will want to make
yann@2173
    10
sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions
yann@2173
    11
from getting into the kernel (which is currently unsupported). At this time,
yann@2173
    12
the kernel build system properly passes those two options, but older kernels
yann@2173
    13
were only passing -mno-spe by default."
