libgcc1: /lib/i386-linux-gnu/libgcc_s.so.1
gcc-4.3: /usr/lib/gcc/i486-linux-gnu/4.3/libgcc_s.so
gcc-4.5: /usr/lib/i386-linux-gnu/gcc/i486-linux-gnu/4.5/libgcc_s.so
gcc-4.6: /usr/lib/i386-linux-gnu/gcc/i486-linux-gnu/4.6/libgcc_s.so
gcc-4.4: /usr/lib/i386-linux-gnu/gcc/i486-linux-gnu/4.4/libgcc_s.so

There is a problem here:

$ ls -l /usr/lib/gcc/i486-linux-gnu/4.3/libgcc_s.so
lrwxrwxrwx 1 root root 18 2011-03-30 22:31 /usr/lib/gcc/i486-linux-gnu/4.3/libgcc_s.so -> /lib/libgcc_s.so.1

This symlink is broken.

Actually, gcc-4.3 is removed from testing and unstable, and it doesn't
work anymore either:

$ gcc-4.3 test.c
/usr/bin/ld: cannot find crt1.o: No such file or directory
/usr/bin/ld: cannot find crti.o: No such file or directory
/usr/bin/ld: cannot find -lgcc_s
collect2: ld returned 1 exit status

So clang probably needs to be rebuilt against a newer gcc.
