3.7.1p1 (possibly p2, too): two small compilation nits on RedHats

[Ville Herva]

(These are compiling the .src.rpm from 
ftp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/rpm/SRPMS/openssh-3.7.1p1-1.src.rpm)

1) On Red Hat 7.3, with gcc-3.2 with the SSP patch 
   (http://www.research.ibm.com/trl/projects/security/ssp/),
  
     rpm --rebuild --define "static_libcrypto 1" openssh-3.7.1p1-1.src.rpm
  
   - I needed to add -ldl to the linker flags before it linked.

2) On Red Hat 5.2, with gcc-2.7.2.3, kernel 2.2.20
  
      rpm -bb openssh-3.7.1p1.src.rpm

   - openbsd-compat/bsd-getpeereid.c didn't find the struct ucred definition
   from /usr/include/linux/socket.h, where it is defined. The reason
   is that linux/socket.h comes from kernel-2.2.x, and sys/socket.h
   (that openssh includes) comes from glibc-devel-2.0.7-29.4, and does not
   include linux/socket.h (and probably assumes kernel-2.0).

   I don't know if configure should pick this up... Probably not.
   I ended up adding the ucred defintion to sys/socket.h because I 
   happened to be in a hurry...

(I admit that I didn't check -p2, but I assume these are not changed since
p1.)

BTW: Does -p2 include the Solar Designer fixes
(http://cve.mitre.org/cgi-bin/cvename.cgi?name=CAN-2003-0682)?
