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.

Without this patch, the sec script that processed initfini.s removes a
yann@1201
    11
part of inlined call_gmon_start, causing undefined label errors.

This patch solves the problem by forcing gcc not to inline
yann@1201
    14
call_gmon_start with __attribute__ ((noinline)).
