I did configure as follows...


-- GDB for host ---

1. $ tar zxvf gdb-5.2.tar.gz
2. $ mkdir /home/tanaka/work
3. $ cd /home/tanaka/work
4. $ ./../gdb-5.2/configure --target=arm-linux --host=i586-linux 
--prefix=/tools
5. $ make
6. $ su
7. # make install


-- GDBserver ---

1. $ mkdir /home/tanaka/work_server
2. $ cd /home/tanaka/work_server
3. $ ./../gdb-5.2/gdb/gdbserver/configure arm-linux
4. $ make
5. $ su
6. # make install


I missed doing configure?
