Hi Anders,

I now tested it and it turns out that test cases for gpio-tools run
from the top source directory don't work anymore because the path to
executables is no longer figured out dynamically depending on
program_invocation_name. You may need to add a config switch that -
depending on --enable-install-tests either does what we're doing now,
or uses your approach.

Best regards,
