RESULT_TOP is where the tools will be installed. It also
affects the prefix used when building the tools which is
used in library searches when the tools run. (typically
for libiconv)

If you don't have permission to write to $RESULT_TOP,
things will fail.

So, if you can't do, say "touch /opt/cross/x" or
"touch /opt/crosstools/x" when the directories
have been created, your build will fail.

One of the first things the script tries to do is
to create the RESULT_TOP directory. It's ok if
it already exists, as long as you have write permission
to it.
