[config] Warn againt using ash as CONFIG_SHELL

It apears that more and more ./configure scripts and Makefiles
make use of non-POSIXly correct shell constructs, that don't
work with ash.

For now, just warn the user against using ash, but keep it as
an option in case newer versions of the /broken/ components
come fixed, and we can again use ash, as it is in some cases
really faster than bash.

    10       Add support for the Signal Processing Engine.  This will set up

    11       the toolchain so that it supports the SPE ABI extensions. This

    12       mainly targets Freescale e500 processors.

    13 

    14       Setting this option will append "spe" to the end of your target

    15       tuple name (e.g., powerpc-e500v2-linux-gnuspe) so that the gcc

    16       configure/build system will know to include SPE ABI support.

    17       It will also automatically add "-mabi=spe -mspe" to your

    18       TARGET_CFLAGS, and "--enable-e500_double" to your CC_EXTRA_CONFIG,

    19       so you do not need to explicitly add them.
