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.

     1 Fix building gfortran for ARM.
     2 http://gcc.gnu.org/ml/gcc-patches/2007-05/msg01010.html

     5 The patch below fixes a crash building libgfortran on arm-linux-gnueabi.
     6 
     7 This target doesn't really have a 128-bit integer type, however it does use 
     8 TImode to represent the return value of certain special ABI defined library 
     9 functions. This results in type_for_size(TImode) being called.
    10 
    11 Because TImode deosn't correspond to any gfortran integer kind 
    12 gfc_type_for_size returns NULL and we segfault shortly after.
    13 
    14 The patch below fixes this by making gfc_type_for_size handle TImode in the 
    15 same way as the C frontend.
    16 
    17 Tested on x86_64-linux and arm-linux-gnueabi.
    18 Applied to trunk.
