Bug#615783: t38modem: ftbfs with gold or ld --no-add-needed

[Matthias Klose]

Package: t38modem
Version: 1.2.0-1
Severity: important
Tags: sid
User: peter.fritzsche at gmx.de
Usertags: no-add-needed

The package fails to build in a test rebuild on at least amd64 with
ld --no-add-needed.  For details, please see:
http://lists.debian.org/debian-devel-announce/2011/02/msg00011.html
http://wiki.debian.org/ToolChain/DSOLinking

Ubuntu might have a patch for this issue, but unfortunately it was
not forwarded to Debian.  Please have a look at
http://packages.qa.debian.org/t38modem to see if an Ubuntu version for
this package exists, and if a fix is included in the Ubuntu diff.
