This is the same patch I put up for review two weeks ago. I got one
positive comment back and nothing else, so I presume nobody has a
problem with it. I've been running with it for a while but have only
tested it with a few linux applications (Java (jre, jdk), and the oracle
installer stuff).

This patch fixes #! paths in scripts run under linux emulation, causing
/compat/linux to be searched for the script binary when the script
is exec'd from a program running under emulation.
Often linux applications run scripts to do various things. Without
this patch these scripts effectively 'break out' of the linux emulation
(for example, use the FreeBSD version of /bin/sh instead of the linux
version of /bin/sh) which can cause compatibility problems, especially
when the scripts run other utilities that they expect to be the linux
version rather then FreeBSD version (install, cat, grep, etc...)
I intend to commit this to -current and immediately MFC it to -stable.
I don't expect there to be any controversy though I'm sure there is a
cleaner way to do it.
-Matt
