possible typo in config.sub

[Robert Lipe]

Around line 734 of this shell, we're in a big old case statement
and we do
              | -udi* | -eabi* | -lites* | -ieee* | -go32* | -aux* \
              | -cygwin32* | -pe* | -psos* | -moss* | -proelf* | -rtems* \
              | -win32* | -mingw32* | -linux-gnu* | -uxpv* | -beos* )
              | -mingw32* | -linux-gnu* | -uxpv* | -beos* )

I just deleted the last of the lines cited.

In light of the 7/27 ChangeLog, This seems like an inarguable fix, so
I've committed this.  If you want to argue about it, feel free. :-)

I don't see this problem in the egcs-release tree, but it's probably
wise to check.
