This is 7e585ded0f1cce41fd3dec6146526d07783d2d38 again,
removed in 981e63a40a5918135f3547c849394a36f8012af9, probably by mistake.
With the linking it's possible that soffice.bin becomes the wrapper
script that ends up calling itself recursively.

install to %libdir% intead of %prefix% as it is usual for other projects;
use the usual DESTDIR instead of OODESTDIR

Note that the default installation path is /usr/local/lib/libreoffice;
it can be redefined by --prefix, --libdir, --with-install-dirname
configure options

needed to fix build on SLED10 with gcc-4.1.2
we want to use @$(extraobjectlist) in the long run

In a from-scratch build, when running the configure script, which then
runs the set_soenv script, the default_images symlink (that is passed
to this function in the form of a Windows path, for some reason) does
not exist yet, and realpath fails anyway. So don't bother calling
realpath on Windows paths.

Although I don't know whether it then will cause a problem that the
cygpath -m call won't be able to expand the symlink as it doesn't
exist anyway. This is a mess. And if cygpath -m expands symlinks
anyway, why is the realpath needed at all?

This is to allow use of ccache by specifying something like:

  export CC="ccache C:/path/to/cl.exe"
  export CXX="ccache C:/patch/to/cl.exe"

before running ./autogen.sh

otherwise a removed file would be recreated

+ use "git log" again to get weekly commit logs
+ use "git rev-list" only with --rev-list option; useful to list differences
  between branches
