With libraries and root filesystem size in mind, I'm trying to link
some programs with libc5 instead of libc6 on my RH60 system.
Unfortunately, I'm not having any success.  As an example, I do the
following:

  hello> gcc -nostdlib -L/usr/i486-linux-libc5/lib -lc -o hello hello.c
  ld: warning: cannot find entry symbol _start; defaulting to 08048184
  hello> ldd hello
          libc.so.6 => /lib/libc.so.6 (0x40016000)
          /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
  hello> ./hello

  Hello, world!

  Segmentation fault (core dumped)

  hello>

Any pointers on how I can do this correctly.  =)
