That's a good start, but there is still some work to be done:
- The minimum dependencies on sparc should be 2.6-1 due to the SPARCV8
to SPARCV8PLUS ABI transition
- The patch uses symbols versioning to determine the minimal Debian
version, but some symbols have been introduced later in Debian, due to
some build options that weren't enabled or availabled on some
architectures. TLS support is such an example.
- As the symbols versioning in dpkg-shlibdeps only takes care of the
symbols and not at the include headers, one has to search for #define or
enum values that have been added, and bump the minimum version of the
corresponding symbols if this value is uses internally in the glibc.
