[PATCH v4 0/3] OpenRISC gdb port


This is the openrisc port of GDB that has been in openrisc
repositories for a very long time. The main original author
was Jeremy Bennett as can be seen in file copyrights. Others
should also have copyright assignment in place.

This along with the sim patches are the last of what has not
made its way upstream. The patches are based on current gdb
git master branch.

I have run the testsuite and results are as follows:

# of expected passes            19283
# of unexpected failures        406
# of expected failures          29
# of known failures             57
# of unresolved testcases       2
# of untested testcases         181
# of unsupported tests          264
#/build-gdb/gdb/gdb version -nw -nx -data-directory #/build-gdb/gdb/testsuite
