Subject: gcc: upgrade from 4.5.0 to 4.5.1

Removed these patches which are not needed anymore.
  gcc-4.5.0_to_svn_162697.patch.bz2 : All the commits in this patch is
          part of the 4.5.1 branch. So moving to 4.5.1 makes this patch
          obsolete
  gcc_revert_base_version_to_4.5.0.patch: moving to 4.5.1 removes need
          of this patch
  gcc-pr43698-arm-rev-instr.patch: upstream has this fix.

+gcc: add poison parameters detection
+
+Add the logic that, if not configured with "--enable-target-optspace",
+gcc will meet error when build target app with "-Os" option.
+This could avoid potential binary crash.
