Bug#923647: kdevelop-pg-qt is unusable for cross compilation

[Helmut Grohne <helmut@subdivi.de>]

Package: kdevelop-pg-qt
Version: 2.1.0-1
User: helmutg@debian.org
Usertags: rebootstrap
Control: affects -1 + src:kdevelop-php

kdevelop-php fails to cross build from source, because it fails running
kdev-pg-qt with an "Exec format error". Usually, that indicates that
kdevelop-pg-qt needs to be installed for the build architecture. After
doing so, cmake fails to find KDevelop-PG-QtConfig.cmake. Bummer.

We cannot use kdevelop-pg-qt as is for cross compilation as is. Getting
it to support cross building also needs a deeper understanding of what
kdev-pg-qt actually is. The description says that it is a parser
generator, which hints that it would transform (textual) programs. If
that is accurate, it could be moved to a M-A:foreign package.

Assuming that's correct, we could create a new binary package
kdevelop-pg-qt-bin and move /usr/bin/kdev-pg-qt into that package. Then
have kdevelop-pg-qt depend on kdevelop-pg-qt-bin and mark
kdevelop-pg-qt-bin Multi-Arch: foreign. What do you think about that
approach?
