Merge lp:~davidgil-uk/cortex-strings/march-2011-buildissues into lp:cortex-strings

[Dr. David Alan Gilbert]

cortex-strings fails to build on Natty (as on my Panda board).
It hits two problems:
  1) That some of the Bionic code doesn't have IT instructions and it's getting built as Thumb; rather than changing the code in 3rd party tests it seems better to add implicit-it so we can pull in any 3rd party code to test.
  2) The linker is now fussy about library order and the -lrt was in the middle of the link line.
