Hi Nikolay,

One thing I can immediately think of is to use the env utility with the 
-i option.
This is specified by POSIX. The -i option causes env to start with an 
empty
environment, so that only those environment variables specified on the 
env
command line will be present.

    all:
        env -i FOO=bar ... make -C 
/home/nataraj/test/make-ci/zzz/build/postgres

Replace FOO=bar ... by the actual environment variables your Makefile
needs; you almost certainly need to set a PATH, and a few others.
