You can see that the associated call/failure is happening inside APR here, on
line 216:

The issue is that if the library is configured (at build time) to
USE_GETRANDOM, then it assumes that the getrandom() call will be available and
if it fails it becomes a fatal error. On my system, I don't have getrandom()
because I'm running an ancient kernel, but others could (more legitimately)
have the option disabled on a recent custom-built kernel.

I think the correct fix is to not use that build-time option, and go back to
using DEV_RANDOM or whatever was being used previously. Alternatively, at
least document that a kernel with getrandom() support is required to use

I'm not sure exactly when the packaging on this changed, but I know it was
broken in 2.4.46-1 and I *think* it worked in 2.4.43-1, although I can't get a
copy of that to double-check anymore.

This changed in libapr1 1.7, re-assigning to apr. I am not sure about the severity, though. According to the man page, getrandom has been introduced in linux 3.17. Debian 9 already has 4.9 so you have to have a kernel that is from Debian 8 to be affected by this.
