Building wheel for iniconfig failed: Permission denied

The newest iniconfig 1.1.0, and 1.1.1 (with #14), fails on ppc64le / Python 3.7. Other (non-exhaustive) combos pass:

An earlier build with 1.0.1 passed:

also receiving same error for current and previous versions..
error -

[update]- my pipeline was working fine with older versions <1.0.0

More testing narrows it down to ppc64le (at least on Python 3.6-3.9):

https://travis-ci.org/github/hugovk/Pillow/builds/735681024

(It installs fine for Python 3.7, fails for a likely unrelated reason, probably I forgot a dependency.)

[hugovk]

We have a workaround to run sudo chown $USER ~/.cache/pip/wheels on ppc64le, which we already had to do for s390x:

• chown pip wheels cache on ppc64le python-pillow/Pillow#4978

This was originally suggested at:

• https://travis-ci.community/t/permission-issue-while-building-wheels-for-various-python-packages/7822/12

Not sure if this is really an iniconfig issue but rather a Travis one, so I'll close this.

Probably should publish wheels to be sure

[hugovk]

Yes, that sounds like a good idea too 👍
