Bug#824079: qgis: FTBFS on non-Linux: 'TCGETS' was not declared in this scope

[Aaron M. Ucko]

Source: qgis
Version: 2.14.2+dfsg-1
Severity: important
Justification: fails to build from source (but built successfully in the past)

Builds of qgis on kFreeBSD failed:

  /«BUILDDIR»/qgis-2.14.2+dfsg/src/plugins/grass/qtermwidget/kpty.cpp: In member function 'bool KPty::tcGetAttr(termios*) const':

Given the natural similarity to #798053, I presume Hurd builds would
fail in the same fashion if their build dependcies were available.  If
and when qgis transitions to Qt5, the best solution would be to switch
to externally packaged libqtermwidget5-0-dev.  As it stands, though,
please patch the embedded copy.

Thanks!
