gentoo-overlay/dev-perl/GnuPG-Interface/files/GnuPG-Interface-0.520.0-0018-Use-a-short-temporary-homedir-during-the-test-suite.patch

From: Daniel Kahn Gillmor <dkg@fifthhorseman.net>

Subject: Use a short temporary homedir during the test suite

This avoids problems with the length of the path to the homedir as
compared to the size limits of sockaddr_un.sun_path, particularly on
systems where /run/user/$(id -u) is not present or available (such as
many minimalist build environments).
