scripts: check host features with host compiler

Currently, we check host feature in ./configure. This works only for
cross toolchains, but not for canadian toolchains. ./configure has
absolutely no way to know what the host for the toolchain will be;
only the build scripts know.

So, move the headers & libraries checks from ./configure to the build
scripts, early enough in the build, but not before we know the host
compiler and other tools.

MPC8572). It uses eglibc (for e500/SPE patches) and a recent gcc (4.6.0,

for e500v2 DPFP support) and will generate appropriate dual-precision

Note: If building a Linux kernel with this toolchain, you will want to make

sure -mno-spe AND -mspe=no are passed to gcc to prevent SPE ABI/instructions

from getting into the kernel (which is currently unsupported). At this time,

    11
the kernel build system properly passes those two options, but older kernels

    12
were only passing -mno-spe by default."
