https://stackoverflow.com/questions/49074327/python-3-6-fails-to-install-to-non-standard-directory-under-linux
I have a completely insulated boostrapped toolchain+binaries setup (located
under /home/tools) that has been able to build everything that I throw at it.
That includes Python 2.7.14, which built without issue with a simple --prefix.
The lone exception is Python 3.6.4. I had to edit the configure and setup.py
script to patch some of the hardcoded paths that were set to standard /usr
directories (the link to ncursesw was notable). It completely compiled and
built correctly, except failed during the 'make install' installation of pip.
The installation scripts create a pip-build-* directory under /tmp and the
source of the failure seems to be centered around that. It appears when the
directory is first created, it's made with the proper permission mask. But
after failure, I can see it's only user writable (not even readable or
executable).

Here's the section of the strace where it first creates the pip-build-*
directory.
