The change hash-style=gnu happened with gcc-4.1 4.1.2-5 although the
version -7 changes this again to hash-style=both. In the mean time, libc6
2.5-5 bumped its shlibs to avoid problems with packages compiled with a
gcc using hash-style=gnu.


So maybe the problem affects only some architectures which do not support
hash-style=both? What arches do not support this?

For me it would seem wise to keep hash-style=both for the entire lenny
cycle and drop it during the lenny+1 cycle to have a smooth transition on
this aspect.
