Glibc documentation states that it always returns ENOTEMPTY when attempting to remove non empty dirs. However on my system rmdir sets errno to EEXIST which breaks builds of some packages, most notably, libreoffice because one of the tests checks specifically for ENOTEMPTY on Linux and EEXIST on Solaris.
