Bug#894660: qmidinet: excessive debug output on stderr

[John Belmonte]

Package: qmidinet
Severity: important

Dear Maintainer,

Please disable debug flag (passed to dh_auto_configure) in
package build.  It's causing qmidinet to emit debug messages
to stderr on *every* MIDI event.

offending config in Debian rules:
    https://sources.debian.org/src/qmidinet/0.5.0-1/debian/rules/#L17

qmidinet uses ac_debug for verbose debug output:

Thank you
