The default python should installed

Per the Python documentation, when installing multiple Python versions
side-by-side the default Python should be installed with `make install`
and alternate Python versions should be installed with `make
altinstall`.
Don't try to be smarter than setup.py

When properly using `make install` and `make altinstall` when
installing multiple side-by-side Python versions setup.py will do the
right thing.
Add pip to opt-python-27
Add/upgrade pip to opt-python-3
Sort binary_hashes file(s)
Always build python-3 before python-2
Prevent yum install conflicts

When installing multiple Python versions side-by-side with `install`
and `altinstall` but installing into the $PKGROOT location setup.py
will create easy_install and nose tests scripts for each Python
version. Later, when attempting to yum install both RPM’s there will be
a conflict. Prevent this by removing/moving the easy_install and
nosetests scripts created by the opt-python-3 build.
Keep version specific 2to3 scripts

Each Python version in a side-by-side installation has it’s own 2to3
script(s). Don’t break the behavior created by using `make install` and
`make altinstall` when configuring the default and alternate Python
versions.
