[issue27625] "make install" fails when no zlib support available

[Palm Kevin]

New submission from Palm Kevin:

It seems that on linux (red hat), the "make install" fails when no zlib support is available. (I have no zlib installed and I don't want to do so)

I reproduced the problem with both python 3.5.1 and python 3.5.2

The command 'configure' and 'make' produced no errors, but the 'make install' failed with this error message:
if test "xupgrade" != "xno"  ; then \
                case upgrade in \
                        upgrade) ensurepip="--upgrade" ;; \
                        install|*) ensurepip="" ;; \
                esac; \
                LD_LIBRARY_PATH=/usr/ls/tmp/py/Python-3.5.2:/usr/ls/app/python35/lib:./ls/lib:./ls/lib:/usr/molis/uniface9606/common/lib:/usr/molis/dlm/Linux/amd64:/usr/oracle/product/11.2.0/lib:/usr/oracle/product/11.2.0/lib: ./python -E -m ensurepip \
                        $ensurepip --root=/ ; \
        fi

zlib is not required to run Python 3.5, it should thus not be required neither for setting up python.
