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.

     3 reporter_comment="This is a sample config file for Freescale e500v2 processors (e.g., MPC8548,

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

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

     6 floating point instructions by default.

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

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

    10 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."
