gcc: enable poison parameters detection

If not configured with --enable-target-optspace, gcc will report
errors if there is '-Os' optimization in parameters.

This fixes [BUGID #342]

Also add "--enable-target-optspace" option to arm gcc configuration.

+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.
