Please consider the attached patch which adds a udeb for libgcc1 containing
only libgcc_s.so.1. That file is needed for the (directfb based) graphical
installer because of pthread_cancel(). See #373253 for background.

Until now we've been copying libgcc_s.so.1 from the host system at build
time, but it would be much cleaner to install it from a udeb.

I've tested the patch on amd64 and it creates the udeb correctly.

Please review the patch carefully as there may be aspects that I've missed
in the complexity of the build system or arch-specific considerations.

The file/udeb is currently only needed for amd64, i386 and powerpc, but it
seems most logical to just build the udeb for all architectures.

The patch itself looks ok, some other questions:

 - did you consider building the udeb from a separate source package,
   build-depending on gcc-4.4-source? This way you don't need to copy
   the file, and you don't need to add additional constraints for freezes
   on the gcc-4.4 package. You could even copy the whole packaging and
   conditionalize on the source package name for this new source package
   to minimize the maintainance effort and get the updates/patches.

   With --enable-languages=c --disable-bootstrap, the additional build
   time penalty is the extra build of a one stage compiler for gcc.

 - you don't need the package for m68k/hppa yet, but if you do build
   for every architecture anyway, please don't build the package for
   these archs, but libgcc2, libgcc4, and libgcc6 udebs.

 - the patch should be prepared for gcc-4.5 as well.

If there are additional constraints for uploads of the gcc-4.4 source package during freeze times, I would prefer the approach to build the udeb's from a separate source.
