[3.6] bpo-29243: Fix Makefile with respect to --enable-optimizations (GH-1478) (#1518)

* bpo-29243: Fix Makefile with respect to --enable-optimizations (#1478) * bpo-29243: Fix Makefile with respect to --enable-optimizations When using the Profile Guided Optimization (./configure --enable-optimizations) Python is built not only during `make` but rebuilt again during `make test`, `make install` and others. This patch fixes the issue. Note that this fix produces no change at all in the Makefile if configure is run witout --enable-optimizations. * !squash (cherry picked from commit a1054c3) * [3.6] bpo-29243: Fix Makefile with respect to --enable-optimizations (GH-1478) * bpo-29243: Fix Makefile with respect to --enable-optimizations When using the Profile Guided Optimization (./configure --enable-optimizations) Python is built not only during `make` but rebuilt again during `make test`, `make install` and others.
