Small patch for Hurd

This patch is because Hurd does not support NOFILE. It is against current
cvs.

The Debian bug report says, "The upstream source makes use of NOFILE
unconditionalized. As the Hurd doesn't have an arbitrary limit on the
number of open files, this is not defined. But _SC_OPEN_MAX works fine
and returns 1024 (applications can increase this as they want), so I
suggest the below diff. Please forward this upstream, too."

========================================
"Love is patient, love is kind. It does not envy, it
does not boast, it is not proud. It is not rude, it is
not self seeking, it is not easily angered, it keeps
no record of wrongs. Love does not delight in evil but
rejoices with the truth. It always protects, always
trusts, always hopes, always perseveres."
I Corinthians 13:4-7
