[patch] XGATE CPU Support

[Sean Keys <skeys at ipdatasys dot com>]

Please find attached an updated patch that adds support for the XGATE 
CPU. I made a couple of code formating fixes as per the GNU coding 
standards since my last posting.

This patch differs from my previous ones in that it contains absolutely 
no change to the m68hc1x code base. Because of this it is of zero-risk 
to existing users of that port requiring stability in their builds. In 
order to link files for both cores into a single loadable binary image, 
simply build the linker with both necessary targets enabled and use the 
--no-warn-mismatch flag.

I've tried multiple times to work with James to produce a collective 
patch, however he's not interested in that. I hope that this standalone 
patch facilitates easier merging of his work with mine in the future.

I have performed the following tests on my dev system.

  gcc (Ubuntu/Linaro 4.6.1-9ubuntu3 i386) 4.6.1

  1. Results with --enable-targets=all:
     make[1]: Nothing to be done for `all-target'.
     real    13m53.799s
     user    8m44.333s
     sys    1m4.316s


    (Fixed XGATE entry in ALL_EMULATION_SOURCES since last patch posting.)

2. make check-binutils

        === binutils Summary ===

# of expected passes        131
# of expected failures        2
# of unsupported tests        13

3. make -C gas check
