In unix/linux/sbrk-hack.c, comment out the 'int __libc_multiple_libcs'
line and try again.

After this fix, you'll probably get errors when the examples are
linked, like: "__progname multiply defined" to fix that, apply this
patch to unix/elf/crt1.c.  (While it may not look like much, it turns
__progname into a common symbol in crt1.c).
