Build GDB and GDBServer for SPARC64

On development (e.g. amd64) machine:

cd $HOME 
curl http://ftp.gnu.org/gnu/gdb/gdb-7.11.1.tar.gz | tar xf - 

mkdir -p $HOME/gdb-build 
cd $HOME/gdb-build 

../gdb-7.11.1/configure --prefix $HOME/xgcc --bindir $HOME/bin --target sparc64-sun-solaris2.11 
make -j5 && make install 

On target (e.g. sparc) machine:

cd $HOME/src 
curl http://ftp.gnu.org/gnu/gdb/gdb-7.11.1.tar.gz | gtar xzf - 

zfs create -p rpool/export/home/aram/builds/gdb 
zfs create -p rpool/export/home/aram/builds/gdbserver
