This patch changes gcc's (ld's) linking behavior. It passes
--no-add-needed flag to ld. Because of it ld does not try to find
related libraries for linking, causing link failures. And these
link failures can be fixed by specifying the library to be linked
explicitely on the gcc command line.

So far c++ include path is not relative to "--sysroot", which brings
trouble if we want to use the toolchain in a new environment where
the original build directory generating that toolchain is not
available. It's firstly exposed in multiple SDK sysroots support, and
then in the case when sstate packages are used, where c++ standard
headers are missing because gcc tries to search original build dir.
This patch makes c++ include path now relative to "--sysroot", and
then once "--sysroot" is assigned correctly in new environment, c++
include paths can be searched as expected.

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.
