gcc family : upgrade to 4.5.0

Imported OE patches into the poky recipes.
	- Use elfutils instead of libelf

Converted OE's svn source into tar ball & a patch.

Added a patch to revert the baseversion to 4.5.0

Merge OE & poky extra_oeconf_options

Fix the zlib (inside gcc)  make issue by providing the --with-system-zlib switch in EXTRA_OECONF

Found out that some header file dirs were soft linked to non-existing
locations like c_std. Changed the configure options to point them to
existing locations like c_global.

gcc-cross-canadian_4.5.0: fix configure issue

Thanks to Saul Wold for providing poky gcc patches rebased to the 4.5.0
sources.
