gcc-4.6: Drop gcc-poison-parameters.patch as its not need

Browse Source 
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:

Upstream-Status: Pending
gcc: add poison parameters detection

gcc will meet error when build target app with "-Os" option.
This could avoid potential binary crash.
