here is the version i plan on committing if there's no feedback.  i'd like to 
get this in before the 7.3 branch.

off the top of my head, changes since the v2 patch are:
 - back out any minor changes that need other patches that havent been 
approved yet in common code
 - get dynamic FDPIC ELF working
 - more linux system calls to support gcc testing of FDPIC ELF apps
