Best guess is you do not have the python-dev files installed. See below

This is strange: it seems a problem with the quotes in the shell. What
is the shell used by your appliance?

The command seems ok in itself, but from the errors it seems that
-DPSYCOPG_VERSION= is parsed without accounting for the quotes, so it
stops at the 2.6 and the rest of the string is taken as separate
tokens. Even the closing quote after 'ext)' is joined to the string,
reinforcing the impression.

What happens if you run the above command pasting it in the shell?

It seems that your "gcc" command is a wrapper calling into "gcc.orig".
I suspect there's a bug in that wrapper messing up with the quotes.

Further evidence here:

There's also a hint about how to fix the problem: if arguments are
forwarded using $* in the wrapper, they should be forwarded with "$@"
(with the quotes) instead.

Hi Daniele

Thanks a lot for your support.

Yes, the problem is with gcc wrapper . I have added "" around $@ in gcc wrapper script.
I am able to build 32 bit version psycopg2 module.

Thanks & Regards
Vamsi Krishna
