You should look into config.log to find out why it fails.  Also don't build in
the source directory.  I bet you don't have all the right packages installed to
use gcc.

Now I have ran autoconf and then ./configure. Here is content of config.log

#/usr/local/bin/autoconf -v
# ./configure 
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by configure, which was
generated by GNU Autoconf 2.59.  Invocation command line was

  $ ./configure

gcc: command not found
is a user error, if you don't have a compiler installed, obviously you can't
compile anything.  yum install gcc should cure it (but to build gcc you'll need
some other packages too, like gmp-devel, mpfr-devel etc.).

The problem you're facing is that you didn't read the documentation on
installing GCC, starting at http://gcc.gnu.org/install/ and summarised at
http://gcc.gnu.org/wiki/InstallingGCC

We can't really help you if you don't read the documentation.

The first prerequisite for compiling GCC is a working compiler.  You've told
configure to use CC=gcc but apparently you don't have gcc installed.  That's
not going to work.

If it's a rhel5 box then install the gcc rpm.

Why have you done that?  Where in the GCC installation docs does it say to run
autoconf?  It doesn't, and it explicitly tells you not to run ./configure, and
Andrew also told you not to build in the source directory. Read the docs.
Building a compiler is not like building other software, don't assume you know
how to do it.

I managed to generate a Makefile in objdir then issued a make command from that
directory. After a 10 minute compilation it ended with the below error.

checking for suffix of object files... configure: error: cannot compute suffix
of object files: cannot compile

Note: I don't have any IA64 files/binaries on my host machine where this cross
compilation is going, so I have not setup where to look for target files. Is
this is the reason for this failure.

Though this is not a bug, I want to reopen this case for your valuable
assistance in resolving this issue.
If that is not feasible, I will close the case with out any second thought.

You need to have follow the directorions for building a cross sysroot or have a
sysroot already built.

 ../gcc-4.3.0/configure --target=ia64-redhat-linux --prefix=/opt/ia64gcc/ 
--with-sysroot=/colt102d/

While configuring I see below message, I guess it should be yes. 
"checking whether we are cross compiling... no" 

colt102d directory contains target machine's /usr,/lib directories.
