Correction for the fix for Bug 3508 - Persistent storage support breaks Linux compatibility.
A 2nd `make install' will fail attempting to create symlink libnvmemmory.so already created by 1st install.
Install should pre-emptively delete it.
# This should be equivalent to running regrtest.py from the cmdline.
# It can be especially handy if you're in an interactive shell, e.g.,
# from test import autotest.
from test import regrtest
regrtest.main()
