Bug#632682: kfreebsd-amd64 and /lib64 -> lib symlink
I looked at just commited r4891, and it seems that it breaks
On kfreebsd-amd64, the ELF interpreter is "/lib/ld-kfreebsd-x86-64.so.1",
i.e. it is really in /lib, not in /lib64.
The "lib64 -> lib" symlinks in previous eglibc versions only have been
as defence against broken packages shipping their libs in lib64.
This part of libc.preinst seems to delete our ELF interpreter:
rm -f /lib/$(basename RTLD_SO)
On kfreebsd-amd64 the "lib64 -> lib" symlinks are optional,
but "/lib/ld-kfreebsd-x86-64.so.1" is not ;-)
