[Pkg-ia32-libs-maintainers] More 32 bit libraries, improve search for libs

aptitude shows a number of 32-bit library debian packages for use on
amd64 systems. But the selection of libraries is rather small and I
need a number of additional libs (only shared objects, in order to run
32-bit executables built on a 32-bit system):
libmpg123, libfaac, libfaad, libao, libid3tag
For simplicity, I just copied the shared objects from the 32-bit
system to /usr/lib32 which mostly worked. But I would prefer having
debian packages to be installed instead of just copying into /usr.
So my questions is if it's planned to include more 32-bit libraries
into the amd64 repository?
Some problems and suggestions:
1. I first tried to install the shared objects to /usr/local/lib32 but
then noticed that this directory is obviously not searched by
/lib/ld-linux.so.2 but I can achieve that by using LD_LIBRARY_PATH.
Running strings -a on /lib/ld-linux.so.2 it seems that it also
looks in /etc/ld.so.cache but ldconfig seems to only look for
64-bit libs and puts them into /etc/ld.so.cache. I suggest having
an ldconfig32 which reads /etc/ld.so.conf32 and writes the results
to /etc/ld.so.cache32 and changing /lib/ld-linux.so.2 so that it
2. Just copying libao from a 32-bit Debian system doesn't work, since
it searches /usr/lib/ao/plugins-4 where it only find 64-libs. So
it should probably configure to look in /usr/lib32/ao/plugins-4 and
plugin shared objects should go there. This may be as easy as
if libao is autoconf-based (I haven't yet looked into src).
What is your opinion on this?
