[oe] Solution for building omap3-console-image using gcc-4.5

[Elvis Dowson]

Hi,
      I've managed to build the omap3-console-image using gcc-4.5, using the overo-oe overo-2011.03 branch, by following these steps:

Step 01.00: Install the OE metatdata, and check out the overo-2011.03 branch:

$ git clone git://gitorious.org/gumstix-oe/mainline.git
$ git clone git://gitorious.org/gumstix-oe/mainline.git org.openembedded.dev
$ cd org.openembedded.dev
$ git checkout -b overo-2011.03 --track origin/overo-2011.03

The last known working commit id for the OE metadata:

Step 02.00: Set the PREFERRED_VERSION for specific packages that you want to build.

To build using gcc-4.4.1 compiler, edit the local.conf file

#
# Specify the version of gcc that you want to build.
PREFERRED_VERSION_gcc = "4.5"
PREFERRED_VERSION_gcc-cross = "4.5"
PREFERRED_VERSION_gcc-cross-initial = "4.5"
PREFERRED_VERSION_gcc-cross-intermediate = "4.5"

#
# Specify the version of binutils that you want to build.
PREFERRED_VERSION_binutils = "2.21"
PREFERRED_VERSION_binutils-cross = "2.21"

The cross compiler will be located in
${OVEROTOP}/tmp/sysroots/x86_64-linux/usr/armv7a/bin

It is important to specify the correct version of binutils. By default, the overo-2011.03 branch defaults to using binutils-2.18.50.0.7, and you must explicitly specify using binutils-2.21, in order to get gcc-4.5.x to compile properly.
