Well, so can you then aprove the patch attached? Also please try to 
compile gdb with --target=x86_64-unknown-linux and tell me if I can 
remove the "broken" flag from MAINTAINERS if you were successfull.

         * config/i386/tm-x86_64linux.h: New.
         * config/i386/x86-64linux.mt: Add GDB_MULTI_ARCH and TM_FILE
         definitions.

Thanks in advance
