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.

2
3Add the logic that, if not configured with "--enable-target-optspace",
