crosstool-0.28-rc13: add sparc64 support

[Dan Kegel <dank@kegel.com>]

Thanks to some quick help from H.J.Lu and patient
testing by M.H.VanLeeuwen, the 0.28-rc13 snapshot of crosstool now builds
gcc-3.4.0-glibc-2.3.2 cross-compilers targeting sparc64-linux.

Please give it a try and report any problems here or
on the crossgcc mailing list.
You can download it from

Changelog:

0.28-rc13:
      arm:
      * Thanks to mroehner@gmx dot de for his crossgcc post of 9 May 2004,
        which suggested the following changes:
        - got rid of symlinks in patches/glibc-2.3.2 to avoid Windows problems
        - use 2.4 kernel headers until arm can build with 2.6 headers
        - moved contrib/glibc-vfp.patch to patches/glibc-2.3.2,
          as it seems to solve problems even when using hard float

      sparc64:
      * H.J.Lu and M.H.VanLeeuwen helped with http://gcc.gnu.org/PR15345;
        see patches/glibc-2.3.2/glibc-2.3.2-sparc64-dl-machine.patch

      misc:
      * fixed typo in chrootshell.c's die() macro that suppressed error text

0.28-rc12:
      x86_64:
      * added x86_64.config, generated by linux-2.6.5's "make allnoconfig"; seems
        to be needed for glibc-2.3.2 on x86_64 + gcc-3.4.0
      * added patches/linux-2.6.5/linux-2.6.5-x86_64-unistd.patch
        to fix x86_64 build with kernel 2.6.5
