scripts/functions: cvs retrieval first tries the mirror for tarballs

The cvs download helper looks for the local tarballs dir to see if it
can find a pre-downloaded tarball, and if it does not find it, does
the actual fetch to upstream via cvs.

In the process, it does not even try to get a tarball from the local
mirror, which can be useful if the mirror has been pre-populated
manually (or with a previously downloaded tree).

Fake a tarball get with the standard tarball-download helper, but
without specifying any upstream URL, which makes the helper directly
try the LAN mirror.

Of course, if no mirror is specified, no URL wil be available, and
the standard cvs retrieval will kick in.

The gcc-3.x toolchains would contain all the targets by default.  With gcc-4,
yann@552
     3
you have to actually list out the multilibs you want or you will end up with
yann@552
     4
just one when using targets like 'sh4-linux-gnu'.

The resulting toolchain can't even build a kernel as the kernel needs to build
yann@552
     7
with the nofpu flag to be sure that no fpu ops are generated.

Here we restore the gcc-3.x behavior; the additional overhead of building all
yann@552
    10
of these multilibs by default is negligible.
