Commit: RX: Fix some gcc testsuite failures

[Nick Clifton]

Hi Guys,

  I am applying the patch below to the mainline and 4.6 branch sources.
  It fixes a few GCC testsuite failures for the RX target, specifically:

     gcc.dg/20020312-2.c
     gcc.dg/pr28796-2.c
     gcc.dg/torture/builtin-cproj-1.c
     gcc.dg/torture/type-generic-1.c
     gcc.target/rx/pack.c

Cheers
  Nick
