configure: document ignored switches

Autostuff tradiotionnally have some switches to set host, build and
target systems, static or shared libs, and a bunch of others...

In the crosstool-NG case, they do not matter, as crosstool-NG is
just a set of scripts (there are C files, but they are compiled
after installation, at runtime, so it does not count).

     7       Add support for the Signal Processing Engine.  This will set up
     8       the toolchain so that it supports the SPE ABI extensions. This
     9       mainly targets Freescale e500 processors.
    10       
    11       Setting this option will append "spe" to the end of your target
    12       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc
    13       configure/build system will know to include SPE ABI support. It
    14       will also automatically add "-mabi=spe -mspe" to your TARGET_CFLAGS,
    15       and "--enable-e500_double" to your CC_EXTRA_CONFIG_ARRAY, so you
    16       do not need to explicitly add them.
