scripts: leave changelog in build dir, copy to install dir

Users tend to look for the build log in the current working directory,
rather than in the toolchain's installation dir. While bundling the build
log in the toolchain installation dir is nice for distribution and review,
it can be easier to have the build log readily available in the working
directory, as it is quicker to get to it.

So, the build log stays in the working directory until the toolchain is
completely and successfully built, and then a (compressed) copy is made.

scripts: do not chmod u+w the whole source directory

Doing a chmod on the whole source dir after every packages
are extracted can take a hell of a lot of time.

The offending packages are far from legion, and they now
have their own chmod u+w to cleanup their own mess...
