zsh over GNU hurd-0.2 kernel

[Kunihiro Ishiguro <kunihiro@xxxxxxxxx>]

Hi, I compiled zsh-3.0.4 over GNU hurd-0.2 kernel.  It works well, but
configure can't find limit constant header
(/usr/include/resourcebits.h) and rlimits.awk doesn't generate proper
header.  Because GNU libc's definition of RLIMIT_[A-Z]* is done by
enumeration.  Below patch changes configure.in so you have to kick
autconf after applied the patch.
