[ooo-build] --with-srcdir build

Hello, good people,

I would like to explain once again what mean the variable SRCDIR. If one
passes the --with-srcdir option, the SRCDIR will be set to a dedicated
directory where ./download will download tarballs and other files that
are used for build. This is useful if you have several builds coexisting
on the same machine. Because it is saving quite a considerable amount of
space since a lot of the tarballs will be having only one instance on
the disk.

Now, if you don't pass the --with-srcdir option, the SRCDIR will be set
to the subdirectory "src" in ooo-build sources. But this is a
coincidence. If you want to refer to that directory as such, you should
use TOOLSDIR/src. TOOLSDIR/src contains files that are part of ooo-build
tarball and not downloaded during the build process.

Please, keep this in mind because once the SRCDIR and TOOLSDIR/src get
messed up, it is pretty complicated to unwind.

Cheers

Fridrich
