--target is wrong here.

--build is the environment you are compiling on.
--host is the environment the program(s) will run on.
--target is afaik only applicable for binutils, gcc and gdb, and
specifies the system to generate code for (debug in the case of gdb).

The ping problem sounds like either a broken development environment
and/or a broken runtime environment, hard to tell what the problem
is there. strace and LD_DEBUG=help are your friends.

As for cross compiling bash and other autoconf using applications
I've been using a handy little wrapper script for configure. It's
attached to this mail.
