Description of problem:

 Fedora Core 6 contains an rpm called "ElectricFence-2.2.2", but it seems
 to be some strange version that doesn't support disabling the banner that
 EF prints out on startup to stderr.

 Since a lot of test-suites (the git test-suite in particular, but that's
 not anything odd) test that stderr looks a certain way, this makes it useless
 for any such situation, since linking with efence will break the test suite.

 For something that is supposed to help debugging, breaking test-suites is a
 really stupid idea.

Version-Release number of selected component (if applicable):

 It claims to be ElectricFence-2.2.2, but at least the original EF has
 supported EF_DISABLE_BANNER for a looong time, and ElectricFence 2.1.18
 in Debian apparently gets this right. 

How reproducible:

 Totally. Just link a program with ElectricFence using -lefence, and try to
 run it. It outputs a really annoying copyright message to stderr, and you
 cannot disable it with EF_DISABLE_BANNER the way it's supposed to.

Steps to Reproduce:
1. Compile with efence
2. Run with EF_DISABLE_BANNER=1
3. No Profit!
  
Actual results:

 Electric Fence 2.2.0 Copyright (C) 1987-1999 Bruce Perens <bruce@perens.com>

Expected results:

 sweet silence

Additional info:

 Googling for EF_DISABLE_BANNER shows that it existed in 2.1.13. Either it
 got incorrectly dropped, or (more likely) the Fedora package is actually
 based on some really old version, despite calling itself 2.2.2.
