gdb-4.18 make problem !

[bach]

Hi,
 I try to compile the gdb-4.18 in another directory and also for
cross-compiling,  and have a problem.
Here is how I did it:

>From a i386-unknow-freebsd machine, I

1. Create another directory:
mkdir gdb-freebsd
cd gdb-freebsd

2. Compile:
../gdb-4.18/configure --prefix=/home/bach/GDB/gdb-freebsd
--srcdir=/home/bach/GDB/gdb-4.18 --target=i386-unknown-netbsd
--host=i386-unhnow-freebsd

Error message:
