zlib: DESTDIR ought to be absolute path
zlib: use arch-specific ar and ranlib
Merge remote-tracking branch 'origin/master'
Merge branch 'standalone' (independent builds)

It is possible to build coastline packages even if the original source
tree is configured for different architecture or not configured at all.

Also added commands to initialize automatically the build directory and
update it.
Simplify installation/packaging

Now, each harbour install the files into an overlay structure that could
be directly copied into /uspace/dist. There is no need for the double
copying into apps/misc/... and then into uspace/dist.

Also, as /uspace/overlay exists, the need for uninstallation routine
does not exist anymore.

The change affects all harbours, but the changes usually reduce the
script complexity.

Merge branch 'archive' (harbour tarballs)
