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.

+ If you say 'y' here, then PREFIX_DIR (above) will be eradicated
+ prior to the toolchain is built.
+ This can be usefull when you are trying different settings (due
+ to build failures or feature tests). In this case, to avoid using
+ a potentially broken previous toolchain, the install location is
+ removed, to start afresh.
+ On the oher hand, if you are building a final toolchain, and install
+ it into a directory with pre-install, unrelated programs, it would be
+ damageable to remove that directory. In this case, you may want to
+ say 'n' here.
+ Note that when acting as a backend, this option is not available, and
+ is forced to 'n'.
