[Build-common-hackers] Bug#379981: cdbs/kde.mk: forbid --enable-final in slow arches

[Adeodato Simó]

Package: cdbs
Version: 0.4.44
Tags: patch

Hi.

The --enable-final option for ./configure that can be enabled by setting
DEB_KDE_ENABLE_FINAL, basically means that instead of:

  % for source in **/*.cpp; do
      g++ -c $source
    done
  % g++ -o binary **/*.o

This is done instead:

  % cat **/*.cpp >_all.cpp
  % g++ -c _all.cpp
  % g++ -o binary _all.o

This results in potentially faster builds, but it is a really big memory
hog. Most of our buildd network copes well, but arm and m68k routinely
suffer from the "killed build after 500 minutes of inactivity" problem.
This is presumably because the machine is busy in swaping like hell.

Please apply the attached patch, in order to have this feature disabled
for those slow arches.

Thanks,
