armel: undefined symbol: __sync_fetch_and_add_4

Adding a python-apt task because we need to upload a workaround and I want to keep this bug open on python-apt to not forget to revert the workaround.

exception propagation support is a new feature in 4.4, not a regression. the implementation is different on arm-linux-gnueabi than on other architectures.

still unknown why the symbol is left undefined.

The gcc 4.4 news mention:
# GCC now supports the __sync_* atomic operations for ARM EABI GNU/Linux.

This bug was fixed in the package gcc-4.4 - 4.4.0-3ubuntu4

Is the python-apt task still needed, or has the workaround (if it was implemented) been reverted already?

I reverted the workaround in bzr.

This bug was fixed in the package python-apt - 0.7.12.1ubuntu1
