gcc-4.6: Drop gcc-poison-parameters.patch as its not need
The gcc-poison-parameters was added specifically to deal with an issue on ppc targets and a bug when we build with -Os -frename-registers. This bug below reports the issue and is fixed in gcc-4.6.x: http://gcc.gnu.org/bugzilla/show_bug.cgi?id=44618 (From OE-Core rev: 0fabe078a31591f41c3fdabe5aa9de1111ef82c7) Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

3gcc: add poison parameters detection

5Add the logic that, if not configured with "--enable-target-optspace",
6gcc will meet error when build target app with "-Os" option.
7This could avoid potential binary crash.
