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.

     1 Original patch from Gentoo.

     3 -= BEGIN original header =-

     4 ARMV5 can use STRD and LDRD access instructions but these accesses need to be

     5 8 byte aligned. The dynamic linker's malloc needs to match this so structures

     6 become 8 byte aligned to void unaligned accesses.
