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.

+The patch below fixes a crash building libgfortran on arm-linux-gnueabi.
+
+This target doesn't really have a 128-bit integer type, however it does use 
+TImode to represent the return value of certain special ABI defined library 
+functions. This results in type_for_size(TImode) being called.
+
+Because TImode deosn't correspond to any gfortran integer kind 
+gfc_type_for_size returns NULL and we segfault shortly after.
+
+The patch below fixes this by making gfc_type_for_size handle TImode in the 
+same way as the C frontend.
+
+Tested on x86_64-linux and arm-linux-gnueabi.
+Applied to trunk.
