config: add an option not to remove the destination directory

In certain circumstances, removing the destination/installation directory
is a bad idea. For example, when the build environment is already taking
care of sanitising the build tree, and pre-installs stuff in there, it is
a very bad idea to remove the destination directory.

This happens now in buildroot, as the crostool-NG backend now installs the
toolchain in the common host-tools directory, and pre-install there a few
host-utilities (eg. host-automake and host-gawk).

Provide a config knob to turn on/off the removal of the destination
directory, defaulting to 'y' (previous behavior), and forced to 'n' when
used as a backend.

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

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

    10       mainly targets Freescale e500 processors.

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

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

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

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

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

    17       so you do not need to explicitly add them.
