Bug#334673: libc6-dev-amd64: Cannot link 64-bit programs

[Daniel Schepler <schepler@math.berkeley.edu>]

Package: libc6-dev-amd64
Severity: important
Version: 2.3.5-7

When I try linking a simple test program in 64-bit mode, I get:

frobnitz:/tmp/buildd# gcc -m64 -o test test.c
/usr/bin/ld: warning: ld-linux-x86-64.so.2, needed by /lib64/libc.so.6, not found (try using -rpath or -rpath-link)
/lib64/libc.so.6: undefined reference to `_rtld_global@GLIBC_PRIVATE'
/lib64/libc.so.6: undefined reference to `__libc_enable_secure@GLIBC_PRIVATE'
/lib64/libc.so.6: undefined reference to `_rtld_global_ro@GLIBC_PRIVATE'

/lib64/libc.so.6: undefined reference to `_dl_argv@GLIBC_PRIVATE'
collect2: ld returned 1 exit status

If I create a symlink /lib/ld-linux-x86-64.so.2 ->
/lib64/ld-linux-x86-64.so.2, the link stage succeeds -- but that might
not be a proper solution in general.  (Especially if it also happens
with other binary dependencies between 64-bit libraries, which I
haven't been able to test.)

I don't know whether this is actually a problem in the glibc, gcc, or
binutils packages -- feel free to reassign, or clone/block, as
appropriate.
