Package libstdc++5-3.3-dbg for powerpc is empty

["Nikita V. Youshchenko" <yoush@cs.msu.su>]

Hello

While debugging cross-compiler build support for powerpc target, I found 
that libstdc++5-3.3-dbg-powerpc-cross package is created empty (without 
library).

I checked and found that libstdc++5-3.3-dbg_3.3.3-9_powerpc.deb currently 
in unstable is empty (file size if 814 bytes).

This is caused by the following lines in debian/rules.defs:

debug_no_archs := powerpc
ifeq ($(DEB_TARGET_ARCH), $(findstring $(DEB_TARGET_ARCH),
$(debug_no_archs)))
    with_debug := disabled for architecure $(DEB_TARGET_ARCH)
endif


I tried to comment pit those lines - and debugging package built ok.
Probably those lines are no longer needed?
