automake fails to build on platforms with Perl >= 5.26

[jayhendren]

Description

On Fedora 28, I tried building an Omnibus project which has automake in the dependency tree, but the automake build failed with a Perl error.

Omnibus Version

6.0.1

Platform Version

Platforms that experience this issue:
